Fig 1. Lymphocyte and eosinophil counts in different groups of illness severity of COVID-19.

Fig 1

(A) The median lymphocyte counts were significantly different among the four groups (P<0.0001). The median lymphocyte count of mild cases was 2.45 (0.98–3.81) × 10⁹/L, which was significantly higher than in general cases (1.12 [0.43–9.54] × 10⁹/L, P<0.01), severe cases (0.77 [0.37–2.26] × 10⁹/L, P<0.001) and critical cases (0.74 [0.17–1.56] × 10⁹/L, P<0.001). The median lymphocyte count of general cases was significantly higher than that of severe cases (Fig 1A, P<0.01). We further compared the association of eosinophil counts and disease severity. (B) The median eosinophil counts were significantly different among the four groups (P = 0.0009). The median eosinophil count of mild cases was 0.09 (0.03–0.3) × 10⁹/L, which was significantly higher than that in the general cases (0.01 [0.00–0.35] × 10⁹/L, P<0.01) and severe cases (0.01 [0.00–0.42] × 10⁹/L, P<0.001), but there was no difference between mild cases and critical cases (0.00 [0.00–0.09] × 10⁹/L). ***, P<0.001; **, P<0.01; *, P<0.05.
