After adjustment for potential confounding and IPTW, measures of association did not change markedly, but were more precise.
CI: confidence interval; IPTW: inverse probability of treatment weighting; LOS: length of stay; OR: odds ratio; RR: relative risk.
a
Adjusted for all confounders summarized in Table 1.
b
Propensity score–weighted log-linear fully adjusted model used to estimate Odds Ratios.
c
Relative risks determined using a fully adjusted, propensity score–weighted log-linear model.
d
With the exception of death, which is estimated directly from the OR, as the event is rare.
