Using Cox regression to model the effect of the HCR-20 total score (scale range 0–40) on length of stay, with age and gender also as covariates, the model yielded is not significant (omnibus test X 2 = 2.962, df = 3, p = 0.398) and no individual covariate approached significance (HCR-20 total score Wald X 2 = 0.359, df = 1, p = 0.549).
