Cumulative incidence of onset and progression of microvascular complications

		Group A (N=3395)	Group B (N=1755)	P value
		n (%)	n (%)	Group A vs B
Diabetic retinopathy	Onset/progression	62 (2.3)	27 (2.0)	0.455
	Onset	43 (2.0)	21 (1.9)	0.687
	Progression	19 (3.6)	6 (3.1)	0.661
Diabetic nephropathy	Onset/progression	76 (3.0)	51 (6.0)	0.147
	Onset	49 (2.6)	37 (6.2)	0.117
	Progression	27 (4.2)	14 (4.9)	0.683
Diabetic neuropathy	Onset/progression	30 (1.1)	13 (1.4)	0.588
	Onset	21 (1.0)	12 (1.7)	0.825
	Progression	9 (1.8)	1 (0.4)	0.142

Cumulative incidence (%) of microvascular complications was calculated per observation period by the Kaplan-Meier method (see online supplemental figure 2). P values were by log-rank test.
