Fig. 6From: Existing evidence on the effects of photovoltaic panels on biodiversity: a systematic map with critical appraisal of study validityProportions of included studies by overall risk of bias and detailed results for each criterion. Note that the total number of studies assessed for each criterion differs as: only observational and modelling studies were checked for the misclassified comparison criterion; only experimental studies were checked for the performance criterion; only studies carrying out a statistical analysis were checked for the outcome assessment criterion; modelling studies were not checked for the exposure criterionBack to article page
