  1. 12 m 12 months, FSSQ Duke-UNC Functional Social Support Questionnaire, FSW female sex worker, ICC Intraclass Correlation Coefficient, IQR inter-quartile range, IVR interviewer, PHQ-9 Patient Health Questionnaire-9, SWC sex work client
  2. a All bivariate regressions included study site fixed effects and interviewer random intercepts. Values for male and female IVR are marginal predicted values based on regression coefficients. b ICC is the proportion of all variance in a model without interviewer gender attributable to variation in interviewer identity; not available for Poisson or ordered logistic models.. P-value is for a χ2 test, adjusted for multiple testing across all results shown in Tables 1, 2, 3 and 4 using the Benjamini-Hochberg method. P-values <0.05 shown in bold
