We founded increasing OR of severity associated with older age (OR = 1.05, 95% CI 1.01-1.09) per year increase, p = .0039), men (OR = 3.19, CI 1.06-9.60, p = .016), one or more comorbidities (OR = 4.36, CI 1.32-14.45, p = .016), CRP > 10 mg/L (OR = 5.47, CI 1.57-19.10, p = .008), and lymphopenia < 0.8 x 109/L (OR = 6.65, CI 1.43-30.92, p = .016). This evidence concerns the gene CRP and lymphopenia.
