patients. In-hospital patient survival (IHPS) probability was 0.843. No significant IHPS difference occurred by stratifying for sex (p¼0.491), BMI (p¼0.103), diabetes (p¼0.874) and techniques (P¼0.98). A significantly better IHPS was found for patients in ASA I/II than III/IV (P< 0.001). Age (P¼0.001), thrombosis (p¼0.017), HA-surgery DT (p¼0.009), coronary artery disease (CAD) (P¼0.032) and chronic kidney disease (CKD) (P¼0.014) resulted as independent predictors for IHPS in the univariate Cox regression and reached statistical significance also in the multivariate Cox regression. Patients age 75 (p¼0.004) and HA-surgery DT 14 days (p¼0.005) were associated with better IHPS in the conditional inference tree of the multivariate Cox model. Conclusion: Age, thrombosis, HA-surgery DT, CAD and CKD were significant predictors for IHPS after PAD surgery. Patients age 75 and HA-surgery DT 14 days were associated with better IHPS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
