Fig. 2 reports the average (pooled) HR and its 95% CI for each of the meta-analysis in muscle invasive bladder tumor. Each figure represents HR of survivin for recurrence-free survival (Fig. 2a), progression-free survival (Fig. 2b), and cancer-specific survival (Fig. 2c) and overall survival (Fig. 2d). The gene discussed is BIRC5; the disease is cancer.
