Correction: Tracking and Monitoring Mood Stability of Patients With Major Depressive Disorder by Machine Learning Models Using Passive Digital Data: Prospective Naturalistic Multicenter Study

In “Tracking and Monitoring Mood Stability of Patients With Major Depressive Disorder by Machine Learning Models Using Passive Digital Data: Prospective Naturalistic Multicenter Study” (JMIR Mhealth Uhealth 2021;9(3):e24365) the authors noted three errors.

1. In the originally published manuscript, there was no equal contribution footnote for authors Ran Bai and Le Xiao. This has been corrected to note that the authors contributed equally to the manuscript.

2. The affiliation for authors Le Xiao, Xuequan Zhu, Nanxi Li, Lei Feng, Gang Wang was incorrectly listed as follows in the original publication:

This has been corrected to the following:

3. The original order of authors was as follows:

Ran Bai^1,2, MS; Le Xiao³, PhD, MD; Yu Guo⁴, MEng; Xuequan Zhu³, MA; Nanxi Li³, MD; Yashen Wang², PhD; Qinqin Chen², PhD; Lei Feng³, PhD, MD; Yinghua Wang², PhD; Xiangyi Yu², MS; Haiyong Xie^1,2, PhD; Gang Wang^1,3, PhD, MD

¹Advanced Innovation Center for Human Brain Protection, Capital Medical University, Beijing, China
²National Engineering Laboratory for Risk Perception and Prevention, Beijing, China
³Beijing Anding Hospital, Capital Medical University, Beijing, China
⁴Beijing University of Posts and Telecommunications, Beijing, China

In the corrected version of the manuscript, Chunxue Wang, Yongdong Hu, and Zhandong Liu have been added as coauthors for their contribution to the design of protocol and data collection. All authors agree with the addition and new order of authors. The revised order of authors is as follows:
