ARTICLE HIGHLIGHTS
Research background
Decompensated liver cirrhosis (DLC) has high mortality, and there are some limitations when applying the common prognostic scores. Nomograms are widely used as prognostic models for many diseases.
Research motivation
Due to the worse prognosis, the overall survival of DLC has attracted much attention from clinicians. Thus, it is necessary to develop a prognostic model to evaluate the outcome of DLC patients.
Research objectives
This study aimed to develop and validate a novel and simple-to-use prognostic nomogram to assess the prognosis of DLC patients.
Research methods
A total of 493 DLC patients were included in this study and divided into a derivation group (n = 329) and a validation group (n = 164). According to the results of univariate and multivariate Cox regression analyses, a nomogram model was developed to predict the prognosis of DLC.
Research results
The nomogram was developed based on age, mechanical ventilation application, model for end-stage liver disease (MELD) score, mean arterial blood pressure and PaO2/FiO2. The C-indexes, calibration curves and decision curve analysis revealed that the nomogram model is a valid tool.
Research conclusions
We constructed a nomogram model that could accurately predict the prognosis of DLC patients and showed better prognostic performance than the CTP and MELD scores.
Research perspectives
This research established a nomogram that could predict prognosis in DLC patients. In addition, the nomogram was precisely evaluated by internal validation, which may be helpful to clinicians in clinical decision making.
