Subgroup analysis of total records to determine the prognostic value of miR-146a-5p in solid cancers. Generally, miR-146a-5p was expressed at low levels in diverse solid cancers and was related to a worse prognosis for patients with cancer (HR 0.875, 95% CI 0.784–0.976). Due to obvious heterogeneity (I² = 64.4%), a random-effects model was used, as indicated in the note shown at the bottom
