Other independent predictors of hospital mortality were ASA-PS (OR 5.17, 95% CI 2.38 to 11.21, P < 0.001, for ASA-PS IV/V patients), high-risk surgery (OR 2.15, 95% CI 1.02 to 4.53, P = 0.043), congestive heart disease (OR 2.90, 95% CI 1.45 to 5.76, P = 0.002), and SAPS II (OR 1.06, 95% CI 1.03 to 1.08, P < 0.001). Here, SKAP2 is linked to congestive heart failure.
