PRIMARY outcome

Timeframe: 2 weeks

Population: Data was analyzed in an intent-to-treat fashion, defined as participants that were randomized and received at least one iTBS session.

Measurement of TBS acceptability, measured using participant retention rates (all-cause discontinuation)

SECONDARY outcome

Timeframe: Baseline and end of double-blind period (2 weeks)

Population: Data was analyzed in an intent-to-treat fashion. Primary outcomes were measured using analysis of variance to compare groups at the end of the 2-week double blind phase. Missing data was addressed using multiple imputation, with 20 imputations or maximum likelihood parameter estimation in mixed model analyses.

Change in the quality of life, using the quality of life questionnaire QLESQ - Quality of Life Enjoyment and Satisfaction Questionnaire (General Quality of Life Index). A self-report scale covering multiple domains (physical health, subjective feelings, leisure time activities, social relationships, treatment satisfaction) The General Quality of Life Index took the mean of all domains. Scores range from 0-5, with higher scores indicating higher quality of life.

SECONDARY outcome

Timeframe: Baseline and end of double-blind period (2 weeks)

Population: Included all subjects who were randomized. Primary outcomes were measured using analysis of variance to compare groups at the end of the 2-week double blind phase. Missing data was addressed using multiple imputation, with 20 imputations or maximum likelihood parameter estimation in mixed model analyses.

Change in PTSD symptoms measured by the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). The CAPS-5 is a structured interview to measure for PTSD symptom change and presence/absence of PTSD, items rated 0 = 'absent' to 4 = 'extreme/incapacitating,' total symptom severity score is calculated by summing severity scores for the 20 DSM-5 PTSD symptoms. Higher scores indicate more severe PTSD symptoms.

Missing data was addressed using multiple imputation, with 20 imputations or maximum likelihood parameter estimation in mixed model analyses.

Change measured using the social/occupational functioning assessment scale (SOFAS). Clinician rating of social \& occupational functioning. Scale of 0-100 with higher scores indicating higher functioning.
