  1. Note:
  2. Quality control: Whether case management interventions were described clearly;
  3. Group comparability: Whether baseline characteristics of the intervention and control groups were similar;
  4. Follow -up rate: Whether the percentage of follow-up was complete;
  5. Dropouts: Whether dropouts were clearly enumerated and/or compared with those completed cases at baseline;
  6. Blinding assessor: Whether assessment was conducted by independent interviewers blinded to group or objective outcomes;
  7. Analysis: Whether intention-to-treat analysis was applied
  8. “+” means “yes”, “-” means “no”, “?” means “no details”
  9. High quality studies: providing full information on all the seven items (follow-up rate being over 90% was regarded as “full information”); moderate quality studies: providing information on at least four items; low quality studies: providing information on fewer than four items.
