CRP and COVID-19: In COVID‐19 patients with hyperglycemia, multivariate regression analysis (Table 3) showed that patients with the blood glucose deterioration (the increase of mid‐term blood glucose levels ≥1.1 mmol/L) are more likely to be severe COVID‐19 than patients with good blood glucose control (aOR, 22.783; 95% CI, 1.661–195.071) after being adjusted for gender, age, BMI, hypertension, diabetes, fever, cough, lymphocyte count, CRP, ESR, fatty liver, LDH, and d‐dimer, even if unadjusted or partially adjusted, patients with the blood glucose deterioration are also more severe cases.
