The relationship between serum IgE and disease relapse. a, b Comparison of the serum IgE levels before and at the disease relapse. c Comparison of baseline serum IgE levels between the patients with and without relapse. (In a, IgE before relapse level was defined as the serum IgE level during the last follow-up period prior to the disease relapse; IgE at relapse was defined as the serum IgE level at the time of disease relapse. In b, the vertical axis represents the IgE levels and the horizontal axis represents every enrolled patient. The two dots on the same vertical dotted line represent IgE levels before and after relapse)
