From: Predicting progression to severe COVID-19 using the PAINT score
ROC analysis was used to evaluate the efficacy of the PAINT score model for predicting COVID-19 patients’ progression from mild/moderate to severe disease. C-index values and the corresponding 95% CIs were estimated for each of the main study time points to assess the score’s discrimination ability. P values represent the statistical significance of the differences between the new score and the other prognostic score or factor
