In “A Smartphone Food Record App Developed for the Dutch National Food Consumption Survey: Relative Validity Study” (JMIR Mhealth Uhealth 2024;12:e50196) the authors noted the following errors in Tables 2 and 5:

Due to an unintended line alignment issue, all values in the DitEetIk! app food record and GloboDiet 24-hour dietary recall (g/d) columns of Table 2 were incorrect for the following rows: Meat, Eggs, Nuts, Milk (products), Cheese, Bread, Cereal products, Potatoes, Drinks, Sandwich spreads, Snacks, Sauces, and Other.

Table 2 has been corrected as follows:

The mean, SD, median, and IQR of consumption of food groupsa as assessed using the DitEetIk! app and 24-hour dietary recalls for the same day and their correlation for the 211 participants with plausible energy intakes.

aFood groups are Wheel of Five food groups—main groups [23]. The food groups Fish, Legumes, and Soups were excluded as the 75th percentile was 0 for both methods. Table 3 provides more information on these food groups.

bWilcoxon signed rank test (normal approximation) of the differences between intake assessed using the DitEetIk! app and the GloboDiet 24-hour dietary recalls for the same day.

Similarly, due to an unintended line alignment issue, all values in the DitEetIk! app evaluation study (g/d) and DNFCS 2019-2021 (g/d) columns of Table 5 were incorrect for the following rows: Meat, Eggs, Nuts, Milk and milk products, Cheese, Bread, Cereal products, Potatoes, Drinks, Sandwich spreads, Soups, Snacks, Sauces, and Other.

Table 5 has been corrected as follows:

Comparison of consumption of food groups assessed using the GloboDiet 24-hour dietary recalls in the DitEetIk! app evaluation study and the first interview in the Dutch National Food Consumption Survey (DNFCS) 2019 to 2021 for a matched group of participants (n=211).

The correction will appear in the online version of the paper on the JMIR Publications website on April 26, 2024, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.
