Table 2

Serum concentrations of IFN-γ, IL-1β, and IL-6 (pg/ml) among patients with alopecia areata (AA), patients with nonsegmental vitiligo (NSV), and healthy controls and a comparison of values in the Mann–Whitney test among AA patients, NSV patients, and healthy controls. Data were considered to be statistically significant at a value of .

	AA patients ()	NSV patients ()	Controls ()	p value (AA patients vs. control)	value (NSV patients vs. control)	value (AA patients vs. NSV patients)
IFN-γ, (pg/ml)
IL-1β, (pg/ml)
IL-6, (pg/ml)

Data are expressed in , mean and standard deviation (SD). IL: interleukin; IFN: interferon.
