CRP and COVID-19: Moreover, Multivariate analysis showed that hemoglobin level (OR, 0.89; 95% CI, 0.81–0.98; p = 0.022), neutrophil counts (OR, 1.80; 95% CI, 1.09–2.97; p = 0.021), and CRP (OR, 1.04; 95% CI, 1.001–1.071; p = 0.043) levels were found to be independent predictors of COVID-19 severity (Table 5).
