HR, hazard ratio; CI, confidence interval; miR-34, microRNA-34.
Data are presented as HR, 95% CI and p value. A p value <0.05 was considered statistically significant. Significance was determined by univariate Cox proportional hazards regression analysis, and all factors with a p value <0.1 were further analyzed by multivariate Cox proportional hazards regression.
