Overall Search Strategy
The search was performed using a combination of the following keywords on July 22, 2020: (“kidney transplantation” or “kidney transplant*” or “renal transplant*”) AND (e‐health or eHealth or m‐health or teleHealth or telemedicine or Internet or Software or website or telemanagement or telecommunications or tele-monitoring) AND (“patient compliance” or “medication adherence” or “noncompliance*”). The search strategies for each database are presented in Multimedia Appendix1. In addition, the search terms used for electronic databases were chosen following the PICO format (P: patients, kidney transplantation; I: intervention, eHealth; C: control [any control interventions], O: outcome [medication adherence]) and modified as necessary to include equivalent terms for each database.
