Note. The overall weighted mean effect sizes are calculated using random-effects models with methods of moments (MM) and full information maximum likelihood (ML) methods to estimate the between-study variance. Weighted mean effect sizes (d+) are positive for differences that favor the transcendental meditation (TM) group relative to controls. Weeks refers to the number of weeks between the last intervention session and the assessment. d+, weighted mean effect size; SE, standard error; CI, confidence interval; SBP, systolic blood pressure; DBP, diastolic blood pressure.
