Levels of antibodies against gonadotropin-releasing hormone (GnRH) in serum in patients and controls

	Diabetes mellitus	Controls	P-value
	N = 39	n = 78
Prevalence IgG antibodies n (%)	6 (15)	0	0.000
Level of IgG antibodies (RU)	2.4 (0.4-1.9)	*	-
Prevalence IgM antibodies n (%)	13 (33)	11 (14)	0.027
Level of IgM antibodies (RU)	1.2 (0.6-5.0)	0.2 (0.1-0.3)	0.000

Antibody levels are presented as relative units (RU), median (interquartile range). n (%) = number and percentage of subjects. * = no IgG antibodies were found. Mann-Whitney U- test or Fisher’s exact test. P < 0.05 was considered statistically significant.
