Figure 3. Summary of quality and risk of bias assessment using Cochrane Collaboration’s tool for assessing risk of bias in randomized trials and adapted Down and Black scoring tool.

Figure 3.

The quality of the selected articles were assessed using two methodological validities: 1) Cochrane Collaboration’s tool for assessing risk of bias in randomized trials [Higgins et al., 2011]. 2) Adapted Down and Black scoring [Downs and Black, 1998] that assess the methodological quality of both randomized and non-randomized studies of health care interventions. A total score of 26 represents the highest study quality.
