A meta-analysis of the expression of TNFRSF4 from six collected microarrays. A The forest plot for the pooled SMD of 0.34 (95% CI: 0.11, 0.57) without a degree of heterogeneity (I2 = 19%, τ2 = 0.0277, p = 0.29). B The funnel plot to assess the possible publication bias of the GEO datasets by Begg’s test with p = 0.348. C The sensitivity analysis for the GEO microarrays results
