As presented in Figure 2(a), the fixed-effects model was applied for no significant heterogeneity existed (I2 = 0.0%; PQ = 0.665); the pooled HR value of OS merged in the eleven eligible articles was 1.73 with the corresponding 95% CI 1.50-1.96 and p < 0.05, suggesting that high level of Capn4 protein, as a prognostic factor of cancer survivors, indicated a shorter OS. Here, CAPNS1 is linked to cancer.
