CRP and diabetes mellitus: Older age (OR: 2.1, p = 0.0002), hypertension (OR: 2.94, p < 0.0001), diabetes mellitus (OR: 1.84, p = 0.0003), a decreased eGFR (OR: 2.38, p < 0.0001), a decreased lymphocyte count (OR: 3.03, p < 0.0001), an elevated LDH level (OR: 3.88, p < 0.0001), an elevated CRP level (OR: 3.29, p < 0.0001), and higher AST and ALT grades (ORs for grade 3 to grade 1 and grade 2 to grade 1: 5.13 and 2.36, p < 0.0001 and p = 0.0002, respectively) were significantly associated with progression to severe disease (Table 3).
