Different multivariate models for 14-day mortality.

*Source was defined as a dichotomous variable as follows. Model 1: high risk source (endocarditis, unknown source, endovascular infections other than catheter-related, central nervous system infections, and respiratory tract infections) vs. low risk source. Model 2: respiratory source vs. other sources. Model 3: catheter-related source vs. other sources. Model 4: Unknown source vs. known source.
The propensity score for including statins was included in all of them. The definition for the variable source was different in each model (see footnote).
