Stepwise variable selection with significance level for entry into the model at 0.1 and with significance level for staying in the model at 0.05 was used.
*Only factors with a significant association at 0.1 in the bivariate model were entered into the multivariate model (n=274).
†Quantitative variables have no reference level. The OR expresses the risk variation for a unit increase of the variable. multivariate composite indicator. Thus, variables not appearing in the multivariate model do not fulfil these selection criteria.
ICU, intensive care unit; SES, self-evaluation of strength.
