CRP and COVID-19: There was a greater probability of dying in patients with severe COVID-19 (OR = 5.65; 95%CI: 1.17–27.25; p = 0.031), older patients (OR = 1.08; 95%CI: 1.04–1.13; p < 0.001), patients who were currently smokers (OR = 3.88; 95%CI: 1.01–16.85; p = 0.049), patients who took anti-CD20 monotherapy (OR = 220.28; 95%CI: 13.07–3713.87; p < 0.001), patients with CRP on day 1 more than 10 (OR = 2.61; 95%CI: 1.01–6.78; p = 0.049) and patients with NLR on day 1 more than 4.82 (OR = 3.92; 95%CI: 1.37–11.2; p = 0.011).
