Integrated expression level of triosephosphate isomerase 1 mRNA in laryngeal squamous cell carcinoma tissue. The mRNA expression level of triosephosphate isomerase 1 (TPI1) was comprehensively calculated using quantitative synthesis. A Forest plot of TPI1 standardized mean difference in laryngeal squamous cell carcinoma tissue. B Funnel plot of publication bias detection (p = 0.9379). C Forest plot of sensitive analysis. Single dataset was omitted one by one to probe the potential source of heterogeneity. D A summary receiver operating characteristic curve with prediction and confidence contours
