The authors of “Treatment Adherence and Secondary Prevention of Ischemic Stroke Among Discharged Patients Using Mobile Phone- and WeChat-Based Improvement Services: Cohort Study” (JMIR Mhealth Uhealth 2020;8(4):e16496) noticed several errors in their published article. The following corrections have been implemented:
In the Abstract, the sentence:
Of the platform registry participants, 88.9% (209/234: 167 hospital-based and 42 community-based participants) adhered to inputting information into WeChat for 8-96 weeks.
Has been corrected to:
Of the platform registry participants, 89.7% (210/234: 167 hospital-based and 43 community-based participants) adhered to inputting information into WeChat for 8-96 weeks.
