  1. 95% confidence intervals in brackets, results of median regression
  2. * p < 0.1, ** p < 0.05, *** p < 0.01
  3. Results of multivariate quantile regressions including a case-control variable as well as CCI, sex, age, and age2 as fixed effects. Column (1) shows the ‘correct’ model, whereas column (2) shows the effect of ignoring the time dependency of exposure. Column (3) shows the results of a regression controlling for overall length of stay instead of matching on the time of infection
