Webpatients at relatively low levels of risk, pairwise hazard ratios were also calculated to compare out-comes between adjacent scores: CAPRA 2 vs. CAPRA 0–1 and CAPRA 3 vs. CAPRA 2. We also calculated the concordance (c) index for the scoring system in this dataset. The c-index in survival analysis is the proportion of randomly paired patients ... In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions characterised by two distinct levels of a treatment variable of interest. For example, in a clinical study of a drug, the treated population may die at twice the rate per unit time of the control population. The hazard ratio would be 2, indicating higher hazard of death from the treatment.
