Risk of bias at outcome level: randomised studies Include all outcomes included in the evidence synthesis. For each study outcome included in the evidence synthesis, state whether: the outcome assessor was blinded intention-to-treat (ITT) was appropriately implemented selective outcome reporting is unlikely the study is free from other (outcome-specific) aspects that affect the risk of bias. The information can be included in a table (see table 23). Table 23: Risk of bias outcome level for [outcome x] Study Blinding of ITT Selective Is the study Overall risk of outcome appropriately outcome free of other bias assessors implemented reporting outcome unlikely specific aspects that can affect the risk of bias Yes/ Yes/ Yes/ Yes/ Low / High no/ no/ no/ no/ unclear unclear unclear unclear Repeat the table for each outcome included in the evidence synthesis. Risk of bias: non-randomised studies Include all studies that were used in the evidence synthesis, including (if applicable) studies of comparator technologies. Include ongoing and unpublished studies if these data are available. Risk of bias assessment results can be displayed separately for each outcome. Therefore separate assessment of risk of bias at the outcome level is not required for non-randomised studies. For each non-randomised study identified, state whether there is:
