Post-mortem histopathological findings in the bone marrow and in the spleen tissue of 11 COVID-19 deceased patients as compared to 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.
