Notes:

^1.All regressions control for the relevant baseline mental health score (i.e. models (1)–(2) control for baseline HSCL, models (3)– (4) control for baseline PHQ9 score, models (5)– (6) control for baseline WHODAS score)

^2.Models (1), (3), (5) do not include interactions; models (2), (4), (6) include study group * site interactions

^3.PR stands for Puerto Rico.
