Forest plots for the different subsets, showing hazard ratios (HR:s) with corresponding 95% confidence intervals (CI:s) for KiGE in univariate analysis (a) and in multivariate analysis (b), adjusted for age at diagnosis and tumor size. The diamonds and the vertical dashed lines represent the overall measures of effect. The areas of the grey squares are proportional to each subset’s weight in the meta-analysis.
