Summary of findings table (sensitivity analysis): interventions… showed no clear difference in studies with gastric cancer participants in addition to eligible… compared with gastric carcinoma; GRADE not reported.
It is very uncertain whether summary of findings table (sensitivity analysis): interventions… changes sensitivity analysis, meta‐regression analysis, first part compared with gastric carcinoma (very low certainty).
Summary of findings table (sensitivity analysis): interventions… led to lower sensitivity analysis, only esophageal and GE‐junction cancer… compared with gastric carcinoma; GRADE not reported.
Summary of findings table (sensitivity analysis): interventions… showed no clear difference in sensitivity analysis, only gastric cancer participants compared with gastric carcinoma; GRADE not reported.
Summary of findings table (sensitivity analysis): interventions… probably leads to lower sensitivity analysis, meta‐regression analysis, second part compared with gastric carcinoma (moderate certainty).
