Dynamic changes in laboratory parameters in 42 COVID-19 patients during hospitalization. A total of 42 patients (25 Wuhan, 17 non-Wuhan) had completed examinations at admission, first follow-up on day 4, and the second follow-up on day 8. The laboratory indicators were analyzed between and within groups during the clinical process (sub-figures a, b, c, d represents Lymphocytes, C-reactive protein, Albumin, and Albumin / globulin ratio respectively). Statistics in the Box Plot were presented as median. The dotted lines indicate the upper and lower normal limits for each parameter. *, P < 0.05; **, P < 0.01; ***, P < 0.001. NR, normal range. Group “Wuhan” indicates patients who lived in or traveled to Wuhan recently. Group “non-Wuhan” indicates patients who had contact with confirmed cases or unknown exposure
