Figure 2

A meta-analysis evaluating the hazard ratio of lncRNA expression and the overall survival of OSCC. (a) The forest plot for evaluating all included studies. was identified as higher heterogeneity, and the random-effect model was used. Publication bias was found, and HRs were adjusted by Duval and Tweedie’s trim-and-fill method. (b) The funnel plot for detecting publication bias. Observed studies were represented by white circles. Possibly missed studies, represented by black circles, were imputed by Duval and Tweedie’s trim-and-fill method. The observed and theoretical combined effect sizes were represented by white and black rhombuses, respectively.
