Combined HRs suggested that survivin overexpression had an unfavorable impact on NSCLC patients' survival with no evidence of any significant publication bias (HR = 2.03, 95%CI: 1.78–2.33, Egger's test, P = 0.24) and no severe heterogeneity between studies (I2 = 26.9%). Here, BIRC5 is linked to non-small cell lung carcinoma.
