A propensity score matching analysis of neutrophil to lymphocyte ratio forecasts the survival of individuals undergoing the transjugular intrahepatic portosystemic shunt

Abstract

ABSTRACT The neutrophil-to-lymphocyte ratio (NLR) has been shown to predict patient outcomes in various disorders. This study was carried out to evaluate the value of NLR in predicting mortality in decompensated cirrhosis patients having transjugular intrahepatic portosystemic shunt (TIPS). The end-stage liver disease model (MELD) is a scoring system to evaluate the liver function reserve. Retrospective investigation was conducted on the clinical information of 244 decompensated cirrhosis individuals with a MELD score ≤15 who underwent TIPS production at two academic medical centres between January 2017 and August 2021. The main result was 12-month post-TIPS mortality. The area under the receiver operating characteristic curve (AUC) was used to investigate the predictive potential of prognostic markers correlated with 12-month mortality using a logistic regression approach. To minimize the effects of potential factors, a 1:2 propensity score matching (PSM) was carried out. The non-surviving group had 21 (8.6%) patients who passed away within 12mo, while the surviving group included 223 (91.4%) patients who survived for more than 12mo. According to the multivariate analyses, NLR>4.8 was an independent prognostic factor of 12-month mortality after PSM analysis (OR=3.4, 95%CI, 1.052-10.985, P =0.041). In comparison to the non-surviving group, the proportion of NLR-high (>4.8) cells in the surviving group were considerably greater (71.4%vs.38.1%, P =0.017). Whether Unmatched group or the Matched group, NLR exhibited the highest diagnostic performance (AUCs of 0.646 and 0.667, respectively, P <0.05). The NLR is a reasonable and effective indicator of 12-month mortality in decompensated cirrhosis patients with a MELD ≤15 receiving TIPS.
