Most patients with severe COVID-19 showed a CRP > 5 mg/dl (100%) and/or Lymphopenia described as lymphocyte < 800 cells/mm2 (91%) (OR for severe COVID-19: 1.4, 95, CI: (1.1–1.6) CPR > 5 mg/dl vs. CRP > 5 mg/dl; p = 0.043; 1.3, 95, CI: (1.1–2) Lymphopenia vs. non-lymphopenia; p = 0.047) (Table 3). Here, CRP is linked to lymphopenia.
