↵a Unless otherwise specified.
↵b Percentage calculated from subsample with relevant variable, not whole sample.
↵c Variables in the multivariate model are those with an OR. Goodness-of-fit of the model: χ2 = 6.41, P = 0.602 (Hosmer–Lemeshow test). Area under the receiver operating characteristic curve = 0.78 (standard error 0.021). CHD = coronary heart disease. CI = confidence interval. COPD = chronic obstructive pulmonary disease. n(%) = absolute frequency (relative frequency). n/m = not in the multivariate model. OR = odds ratio.
