Figure 1.

Ante-mortem laboratory findings from peripheral blood samples that were drawn within the week prior to death from 11 patients with COVID-19 as compared to those of the four control patients.

Note: Red dots represent findings in COVID-19 patients with B cell depletion in either spleen or bone marrow (n = 7), green dots represent findings in COVID-19 patients with B cell preservation (n = 4), black hashes represent findings in the control cohort (n = 4). Centre values represent the median of the entire cohort (n = 15) and error bars indicate the standard deviation of the pooled values. The upper and lower normal limits for each value are charted as grey zones.

Abbreviations and conversion factors: RBC, red blood cell count; MCV, median corpuscular volume; MCH, median corpuscular haemoglobin; PLT, platelets; INR, international normalized ratio (prothrombin time ratio between patient sample and standard sample); aPTT, activated partial thromboplastin time; WBC, white blood cell count; CRP, C-reactive protein (multiply by 9.5238 to convert to nmol/l); IL-6, interleukin 6.
