| 6 October 2021 | Amended | Correction made to the risk of bias assessment for Govaert 1994a. In the 'Characteristics of included studies' for Govaert 1994a, the authors' judgement for each bias in the Risk of Bias table was marked as "low" for each bias, but the description in the justification for the judgment did not correlate. This has now been corrected. |
