Survivors differed from nonsurvivors for being younger, having few preexisting medical conditions (specifically, lower rates of diabetes, hypertension, cardiovascular diseases, chronic respiratory diseases, renal failure, solid tumors, and arteriopathy), more cough and diarrhea at onset but less dyspnea, a longer time from symptoms onset to hospitalization, a higher P/F, albumin and hemoglobin value, a higher platelet count, lower WBC and lymphocyte count, a lower creatinine, BUN, C-reactive protein, and D-dimer. The gene discussed is CRP; the disease is acute kidney injury.
