ITPR1 and neoplasm: In the univariate model, tumor grade (hazard ratio [HR] = 1.114; 95% confidence interval [CI] = 1.0200–1.8594; p =0.0366), ITPR1 expression (hazard ratio [HR] = 0.8443; 95% confidence interval [CI] = 0.7239–0.9847; p =0.0310), and ITPR3 expression (HR = 1.0247; 95% CI = 1.0077–1.0420, p =0.0042) were significantly correlated with OS.
