Review author’s judgments about each risk of bias item across all the included studies. Rating was based on the risk of bias. i.e. “low overall bias”—rated as “A,” “medium overall bias” —rated as “B,” and “high overall bias”—rated as “C”. Subsets were further categorized (i.e. C1.0, C1.1.) according to the bias in the individual domain.
