aThe clinical parameters were statistically analyzed with the maximum or minimal records of each parameter during the course of the disease. The data were presented as mean (95% confidence interval).
bThe atypical lymphocyte morphology was defined as either prolymphocytes or lymphocytes with cleaved nuclei or lymphoplasmacytoid cells by microscope. The data were presented as mean (95% confidence interval).
cVEGF: vascular endothelial growth factor. The level of serum VEGF was statistically analyzed with the maximum value of each patient during the hospitalization. There was no difference between the four different severity groups, .
*There was significant difference of serum VEGF level between the critical group and other group (mild, moderate, or severe) at convalescence stage of the disease, .
