Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Background: To develop and validate a risk-scoring model for predicting severe COVID-19 at presentation.
Methods: Entire patients with COVID-19 in three cities in Zhejiang, China from December 2019 to February 2020 were analyzed retrospectively. The risk-scoring model was developed with nomogram using multivariate logistic regression and externally validated by the patients from two other cities near Wenzhou.
Findings: Severe COVID-19 was detected 58 out of 488 (11·9%) eligible patients in the primary cohort and 24 out of 153 (15·7%) in the validation cohort. The sex (OR 4·11, 95% CI 1·38 to 14·05), body mass index >25 kg/m2 (OR 6·14, 95% CI 2·05 to 21·29), hypertension (OR 4·97, 95% CI 1·73 to 15·37), neutrophil/lymphocyte ratio (3-6) (OR 8·04, 95% CI 2·51 to 29·52), albumin (35-40) g/L (OR 37·96, 95% CI 5·49 to 825·34) and platelets >300×109/L (OR 6·76, 95% CI 1·55 to 32·47) were independent predictors of severe COVID-19. The risk-scoring model-PAINTS performed excellent discrimination with AUC 0·98, 95% CI 0·96 to 1·00 in the primary cohort and AUC 0·78 (95% CI, 0·67 to 0·89) in the validation cohort. Interpretation: PAINTS score may guide clinical decision-making efficiently and allocate limited medical resources reasonably.
