| Aim | To assess the methodological quality (AMSTAR) and risk of bias (ROBIS) in systematic reviews of interventions aimed at improving vaccination coverage indexed up to June 2016. |
| Level of Investigation | Descriptive |
| Summary of Findings | Methodological quality using AMSTAR found 32%, 60% and 9% of the included systematic reviews to have high, moderate and low quality, respectively. Risk of bias using ROBIS found included reviews had 74%, 14% and 12% of low, unclear and high risk of bias. Principal component analysis showed that systematic reviews with low risk of bias in ROBIS correlated with systematic reviews having high-quality in AMSTAR, and systematic reviews with high risk of bias in ROBIS correlated with low-quality systematic reviews in AMSTAR. |
