Kernel density estimates for ISS (A), NISS (B), APACHE II (C), and prothrombin time (D). A: The median ISS value for death at admission was 41.0 (27.0–50.0); followed by those for early death within the first 72 h (median 34.0 [25.0–45.0]) and for survival for > 3 days (median 29.0 [25.0–38.0]). B: The median NISS value for death at admission was 50.0 [41.0–66.0]), followed by those for patients who died within the first 72 h (median 50.0 [41.0–59.0]) and by those who survived for > three days (median 41.0 [29.0–50.0]). C: The median APACHE II score for death at admission was 30.0 (24.0–34.0), followed by those for patients who died within the first 72 h (median 25.0 [20.0–32.0]) and those who survived for > 3 days (median 15.0 [9.0–20.0]). D: The median prothrombin time for the patients who died on the day of admission was 37.0% (25.5–55.0%), increasing with increasing survival time (median 56% [42.0%–76.8%] for those surviving till days 1–3; median 84% [67.0%–100.0%] for those surviving for > 3 days).
