Forest plot for the association between VEGF expression and overall survival of CRC. The squares and horizontal lines represent the HRs and 95% confidence intervals (CIs) in the individual studies; the size of each square represents the weighting assigned to the corresponding study. The diamond indicates the pooled HRs.
