Public versus Private Healthcare Systems following Discharge from the ICU: A Propensity Score-Matched Comparison of Outcomes

Figure 2

Balances of the covariates in the public and private healthcare systems before and after propensity score matching. Note. After propensity score matching, 112 matched pairs were identified. The standardized differences are reported as percentages, and differences ≤ 10.0% indicate relatively small imbalances. ICU: intensive care unit; APACHE-II: acute physiology and chronic health evaluation-II score; SOFA: sequential organ failure assessment score; TISS-28: simplified therapeutic intervention scoring system; RRT: renal replacement therapy.
