Characteristics of the study population

Characteristics	Progr-T1D (N = 23)	Children not progressing to type 1 diabetes
		NP-AAB+ (N = 32)	NP-AAB− (N = 31)
Age at baseline, years	6.17 ± 1.49	7.61 ± 2.42	7.13 ± 2.07
Sex, male	15 (65)	21 (66)	17 (55)
Multiple autoantibodies (≥2)	18 (78)	8 (25)	NA

Data are presented as means ± SD or n (%)

The three groups were comparable in terms of sex, although age was slightly higher in the NP-AAB⁺ group than in the progr-T1D group (p = 0.04). Eighteen (78%) of progr-T1D and 8 (25%) of NP-AAB⁺ children had multiple positive islet autoantibodies
