In this article, there are errors in Figure 2. The risk of bias of the RCTs is not well described because the definitions of the different types of bias used during the analysis process were incorrect.
FIGURE 2.
Risk of bias of randomized controlled trial studies.
The risk of bias for each included RCT, assessed using Cochrane Collaboration RoB1, is summarized in Figure 2 below. Risk of bias in RoB1 is categorized in 6 types of bias as defined below.
Sequence randomization bias: inadequate generation of randomization sequence.
Allocation concealment bias: inadequate concealment of allocations prior to assignment, making the randomization sequence predictable by researchers at the time of participant inclusion.
Performance bias: knowledge of assigned interventions by participants and staff during the study.
Detection bias: knowledge of assigned interventions by outcome assessors.
Attrition bias: amount, nature, or management of incomplete outcome data (e.g., number of dropouts unevenly distributed between groups).
Reporting bias: selective reporting of results.
We apologize for this error.
