LTF, lost to follow-up; NSP, nonspecialist provider; SP, specialist provider; TM, telemedicine; IP, in-person. *Includes one participant who was a screen fail. **Due to the COVID-19 pandemic, recruitment to in-person (NSP–IP and SP–IP) occurred during the following time periods: January 2020 to March 2020, April 2022 to April 2023 and July 2021 to January 2022 (Extended Data Fig. 1). ***Reflects participants who completed the primary outcome (EPDS). ±Per protocol analyses were only conducted for modality (TM versus IP) comparisons because protocol deviations were defined as instances where participants were switched from IP to TM due to the COVID-19 pandemic. ¥Imputed analyses including the full sample (N = 1,230) were also conducted for all ITT and PP analyses (see Extended Data Fig. 2 for a flow chart by condition).
