Summary of the appraisal done on the assessment endpoints for acute exposure laboratory experiments with bees. The outcome takes into account the risk of bias and the precision for several criteria combined with a predefined algorithm (see Annex A). Green indicates low risk of bias or high precision (class 1), yellow moderate risk of bias (class 2 for external and internal validity), while red indicates high risk of bias (class 3) or low precision (class 2)
