Among the patient groups significant differences were reported for PFAPA versus all the other groups as AAE IgA and IgG, JIA versus CD (IgG: P = 0.006), CD versus CrD (IgG: P = 0.003), and CrD versus HPF (IgG: P = 0.025) (See Supplementary Data S1 in supplementary material available online at doi: 10.1155/2011/870214).
