abstract="To identify risk factors and develop a simple model to predict early prognosis of acute paraquat (PQ) poisoning patients, we performed a retrospective cohort study of  acute PQ poisoning patients (n = 1199). Patients (n = 913) with PQ poisoning from  2011 to 2018 were randomly divided into training (n = 609) and test (n = 304)  samples. Another two independent cohorts were used as validation samples for a  different time (n = 207) and site (n = 79). Risk factors were identified using a  logistic model with Markov Chain Monte Carlo (MCMC) simulation and further evaluated  using a latent class analysis. The prediction score was developed based on the  training sample and was evaluated using the testing and validation samples. Eight  factors, including age, ingestion volume, creatine kinase-MB [CK-MB], platelet  [PLT], white blood cell [WBC], neutrophil counts [N], gamma-glutamyl transferase  [GGT], and serum creatinine [Cr] were identified as independent risk indicators of  in-hospital death events. The risk model had C statistics of 0.895 (95% CI  0.855-0.928), 0.891 (95% CI 0.848-0.932), and 0.829 (95% CI 0.455-1.000), and  predictive ranges of 4.6-98.2%, 2.3-94.9%, and 0-12.5% for the test,  validation_time, and validation_site samples, respectively. In the training sample,  the risk model classified 18.4%, 59.9%, and 21.7% of patients into the high-,  average-, and low-risk groups, with corresponding probabilities of 0.985, 0.365, and  0.03 for in-hospital death events. We developed and evaluated a simple risk model to  predict the prognosis of patients with acute PQ poisoning. This risk scoring system  could be helpful for identifying high-risk patients and reducing mortality due to PQ  poisoning.<p /> <p>Language: en</p>",
