Fig. 1From: Dynamic changes in lymphocyte subsets and parallel cytokine levels in patients with severe and critical COVID-19Dynamic changes of lymphocyte subsets in severe and critical COVID-19. Absolute numbers of total lymphocytes (a), T lymphocytes (b), CD4+ T-cells (c) and CD8+ T-cells (d), B cells (e), NK cells (f) were analyzed at different time points after hospital admission.
