CRP and COVID-19: The univariate analysis showed that WBC (HR = 1.033; 95% CI, 1.021–1.044; p < 0.001), AST (HR = 1.021; 95% CI, 1.012–1.031; p < 0.001), CREA (HR = 1.001; 95% CI, 1.000–1.003; p = 0.018), CRP (HR = 1.013; 95% CI, 1.007–1.019; p < 0.001), and ENA positivity (HR = 2.575; 95% CI, 1.399–4.739; p = 0.002) were related to the outcomes of COVID-19 patients (Table 3).
