CONSORT-EHEALTH (V 1.6.1) - Submission/Publication

The CONSORT-EHEALTH checklist is intended for authors of randomized trials evaluating web-based and Internet-based applications/interventions, including mobile interventions, electronic games (incl multiplayer games), social media, certain telehealth applications, and other interactive and/or networked electronic applications. Some of the items (e.g. all subitems under item 5 description of the intervention) may also be applicable for other study designs.


1a-i) Identify the mode of delivery in the title
Identify the mode of delivery. Preferably use "web-based" and/or "mobile" and/or "electronic game" in the title. Avoid ambiguous terms like "online", "virtual", "interactive". Use "Internet-based" only if Intervention includes non-web-based Internet components (e.g. email), use "computer-based" or "electronic" only if offline products are used. Use "virtual" only in the context of "virtual reality" (3-D worlds). Use "online" only in the context of "online support groups". Complement or substitute product names with broader terms for the class of products (such as "mobile" or "smart phone" instead of "iphone"), especially if the application runs on different platforms.

1b-ii) Level of human involvement in the METHODS section of the ABSTRACT
Clarify the level of human involvement in the abstract, e.g., use phrases like "fully automated" vs. "therapist/nurse/care provider/physician-assisted" (mention number and expertise of providers involved, if any). (Note: Only report in the abstract what the main paper is reporting.

Copy and paste relevant sections from the manuscript abstract (include quotes in quotation marks "like this" to indicate direct quotes from your manuscript), or elaborate on this item by providing additional information not in the ms, or briefly explain why the item is not applicable/relevant for your study Both interventions were provided face-to-face. Also, participants received regular follow-up calls during the trial to monitor adherence and address any concerns or problems. These phone calls were made by an investigator member of the research team.
1b-iii) Open vs. closed, web-based (self-assessment) vs. face-to-face assessments in the METHODS section of the ABSTRACT Mention how participants were recruited (online vs. offline), e.g., from an open access website or from a clinic or a closed online user group (closed usergroup trial), and clarify if this was a purely web-based trial, or there were face-to-face components (as part of the intervention or for assessment). Clearly say if outcomes were self-assessed through questionnaires (as common in web-based trials). Note: In traditional offline trials, an open trial (open-label trial) is a type of clinical trial in which both the researchers and participants know which treatment is being administered. To avoid confusion, use "blinded" or "unblinded" to indicated the level of blinding instead of "open", as "open" in web-based trials usually refers to "open access" (i.e. participants can self-enrol).

Users of the app had to report their pain intensity twice a day (before and after the exercise program) and respond to self-reported outcome questionnaires once a week. The load and intensity of the exercises were automatically adapted to each participant's pain intensity [41][42][43] (Figure 2). The CareHand app includes an exercise diary with a graphical representation of the progress in the planned treatment protocol, and the evolution of pain intensity. This diary helps to promote positive self-management routines, monitor long-term adherence, and collect patients' feedback [12,38]. The app also provides advice about diet and rules for joint protection. Educational and self-management strategies to handle RA related symptoms and improve function during activities of daily living (ADL), along with recommendations for regular physical activity, were also given ( Figure 2)

5-ix) Describe use parameters

Data are reported as mean (standard deviations or 95% confidence interval), or as percentages. The Shapiro-wilk test was used to evaluate the normal distribution of the study measures. Mean outcome differences after intervention were compared using a repeated-measures analysis of variance (ANOVA), with group (Control vs CareHand) as the between-subjects factor, and time (baseline, first, third-and sixth-month follow-up) as the within-subjects factor. When the assumption of sphericity was violated, the Greenhouse-Heisser correction was applied. Partial eta squared values estimate the effect size. Statistical significance was set to a P value <.05."

12a-i) Imputation techniques to deal with attrition / missing values
Imputation techniques to deal with attrition / missing values: Not all participants will use the intervention/comparator as intended and attrition is typically high in ehealth trials. Specify how participants who did not use the application or dropped out from the trial were treated in the statistical analysis (a complete case analysis is strongly discouraged, and simple imputation techniques such as LOCF may also be problematic [4]).

This does not only refer to metrics of attrition (13-b) (often a binary variable), but also to more continuous exposure metrics such as "average session length". These must be accompanied by a technical description how a metric like a "session" is defined (e.g., timeout after idle time) [1] (report under item 6a).

A subgroup analysis of comparing only users is not uncommon in ehealth trials, but if done, it must be stressed that this is a self-selected sample and no longer an unbiased sample from a randomized trial (see 16-iii).

However, no differences between groups were demonstrated for self-reported pain and morning stiffness, grip and pinch strength, and upper limb function, thus results must be interpreted cautiously. " Also, future research may analyze the cost-effectiveness of the intervention.

20-i) Typical limitations in ehealth trials
Typical limitations in ehealth trials: Participants in ehealth trials are rarely blinded. Ehealth trials often look at a multiplicity of outcomes, increasing risk for a Type I error. Discuss biases due to non-use of the intervention/usability issues, biases through informed consent procedures, unexpected events.

The sample size was rather small, although relevant for the study aim and clinical purposes. Despite the multicenter design, participants were selected from a rural setting, which could limit the external validity of the findings. Changes in the study measures were evaluated in a medium-term follow-up (6 months), but a longterm assessment is needed to better understand the efficacy of digital tools, and the impact of the strategies used to engage patients. Important factors, such as self-efficacy, psychological aspects, and treatment adherence were not measured. At baseline, both groups differed in the pain and satisfaction subscales of the MHQ, which may be a source of bias. Also, due to the restrictions imposed by the COVID-19 pandemic, some of the outcomes were collected via telephone. Finally, the normal course of RA includes periods of remission and exacerbation of symptoms, which can affect self-reported data. "

This app, developed with feedback from patients and health professionals, allows clinicians to treat people with RA, monitor their symptoms, evolution, and engagement with intervention. The app features foster a proactive selfmanagement. This may enhance self-efficacy and empower patients, which is key to handle chronic musculoskeletal disorders [82]. The feedback features also allows for a quick response if a disease flare up appears [83]. The wide use of mobile devices and its portability represent a great potential impact for this app on healthcare delivery processes [66]. When implemented in the clinical setting, the CareHand app could reduce unnecessary visits to medical centers, as observed with other telehealth strategies in RA [84], with the subsequent economic implications."

Discuss if there were elements in the RCT that would be different in a routine application setting (e.g., prompts/reminders, more human involvement, training sessions or other co-interventions) and what impact the omission of these elements could have on use, adoption, or outcomes if the intervention is applied outside of a RCT setting.
