PROBAST, Prediction model Risk Of Bias ASsessment Tool.
In the risk of bias assessment, low means low risk of bias, high means high risk of bias, and unclear when it was not possible to assess the risk of bias. In the applicability section, high means high concern for applicability, low means low concern for applicability, and uncertain when it was not possible to assess the applicability. Risk of bias conducted with the PROBAST tool 16, 17, 18.
