Independent predictive risk factors for disease severity
The severe and critical groups were determined as severe and the moderate group as non-severe. Age, erythrocyturia, proteinuria, and glucosuria were significantly higher parameters in the severe group than the non-severe group (p<0.001). On multivariate analysis, proteinuria (OR: 4.66, 95%CI 1.02-21.4, p=0.047) and age (OR: 1.06, 95% CI 1.03-1.10, p<0.001) were independent predictive factors for disease severity (Table 2). The optimum cut-off value of age for predicting severe disease was 59.5 years. AUC of age was 0.828 [95%CI (0.756-0.899); P<0.001]. The highest sensitivity and specificity were 0.771 and 0.765 for age (Figure 1).
