	≤18 years	30.3 (n = 995)	33.2 (n = 769)
Diabetes symptoms, %
	Weight loss	1.6	2.1
	Polyuria	0.5	0.7

	Fatigue/loss of power	2.2	3.3

Data are median with lower and upper quartile for continuous variables, and percentage for dichotomous variables. For patients ≤18 years, standard deviation scores are shown for height, weight and body mass index. Weight and height measurements (and thereby body mass index, percentage underweight) were missing in few patients. Abbreviations: OGTT = oral glucose tolerance test, SDS = standard deviation score.
