Crude and standardised incident event and mortality rates among individuals with type 2 diabetes mellitus, VIP 1992–2013

Variable	Deaths			CVD events			Renal disease			Retinopathy
	n	MR	StdMR	n	IR	StdIR	n	IR	StdIR	n	IR	StdIR
Confirmed screen-detected diabetes	73	8.2	4.2	128	15.5	8.7	39	4.4	3.3	70	8.1	6.3
Unconfirmed screen-positive individuals	139	10.4	5.9	141	11.0	5.8	23	1.7	0.9	9	0.7	0.4

Incidence rate and mortality rate are reported per 1000 person-years. Age- and sex-standardised mortality rate and incidence rate are calculated with the total study population as reference

Rates do not include events that coincide with the date of diabetes detection

CVD, renal and retinal events were detected in the National Patient Register and the Cause of Death Register

Unconfirmed screen-positive individuals only had a diabetic screening result, whereas confirmed screen-detected individuals had a diabetic screening result and a medical or prescription record of diabetes within 1 year. Those with clinically detected diabetes were identified in five sources of medical and prescription records, unrelated to screening

IR, incidence rate; MR, mortality rate; StdIR, standardised incidence rate; StdMR, standardised mortality rate
