In the multivariate analysis, high PARP9 expression in patients was independently associated with overall survival (HR = 1.04, 95% CI 1.01‐1.07, P = .009), together with tumor status (HR = 23.64, 95% CI 3.29‐169.85, P = .002) and histological type (HR = 2.02, 95% CI 1.63‐2.49, P < .001). The gene discussed is PARP9; the disease is neoplasm.
