Subgroup analysis by tumor type to show the prognostic value of miR-146a-5p in diverse tumors. In the subgroup analysis, decreased miR-146a-5p expression in gastric cancer (GC) was associated with shorter overall survival (HR 0.535, 95% CI 0.327–0.877). The random-effects model was applied as noted above (I2 = 64.40%)
