IR and MR reported per 1,000 person-years. Age and sex standardised MR and IR are calculated with the total study population as reference.
Rates do not include events that coincide with date of diabetes detection.
CVD, renal and retinal events detected in Hospital Outpatient and Inpatient Discharge Registers, and the Cause of Death Register.
Unconfirmed screen-positive cases had only a diabetic screening result, whereas confirmed screen-detected cases had a diabetic screening result and a medical or prescription record of diabetes within one year. Clinically detected diabetes cases were identified in five sources of medical and prescription records, unrelated to screening.
CVD: Cardiovascular disease, IR: Incidence rate, MR: Mortality rate, OGTT: Oral glucose tolerance test, StdIR; Standardised Incidence Rate, StdMR: Standardised Mortality Rate.
