Treatment effects of rTMS estimated from logistic regressions for binary outcomes adjusted for PTSD, substance use, and site; estimated from general linear regressions for continuous outcomes adjusted for baseline; and presented in the Table as odds ratios (95% CI from the logistic regressions and treatment coefficients (95% CI) from the general linear regressions.
The HRSD remission rates were calculated based on 164 randomized participants. If the HRSD score was missing, the participant was considered as not achieving remission based on the protocol.
