From: Prevalence and sociodemographic correlates of common mental disorders among first-year university students in post-apartheid South Africa: implications for a public mental health approach to student wellness

  Predictor Distribution in total sample % Prevalence rates Odds Ratios for number or risk factors as predictors of prevalence
  Prevalence of any lifetime disorder for each level of risk % Prevalence of any 12-month disorder for each level of risk % 12-month Prevalence among Lifetime Cases for any disorder for each level of risk % Any lifetime disorder OR (95%CI) Any 12-month disorder OR (95%CI) 12-month Prevalence among Lifetime Cases OR (95%CI)
