In the original version of the article, the below two sentences along with the subtitle “Assessment of risk of bias in included studies” were inadvertently repeated. The duplicate sentences were now removed.


Assessment of risk of bias in included studies


Two review authors (MAG and JFM) independently assessed the risk of bias for each of the selected studies using the Cochrane Collaboration Risk of Bias Tool [27]. Any disagreement was resolved by involving a third reviewer (WP).

The original article has been corrected.
