The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes.
The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: Confidence interval; RR: Risk ratio;
Quality of evidence was downgraded by 1 point owing to unclear risk of performance bias and unclear selective reporting
Sample had <66% pancreatic cancer patients.
95% CI crosses 1 default MID (0.8 or 1.25).
95% CI crosses 2 default MIDs (0.8 and 1.25).
MIDs for nutritional status (gastric emptying time) were calculated as +/- SD of control group immediately after resumption of oral diet and was +/- 75.91 min.
95% CI crosses 1 MID for this outcome.
