Table 1. Simulated health check strategies and control.

	Eligibility criteria for risk assessments, for individuals offered a health check
Strategy	Diabetes risk assessment*	Lipid risk assessment	Lifestyle Interventions†
Control – No health checks offered	None	None	None
Health check – base-case	All	All	All
Health check without lifestyle interventions	All	All	None
Health check with gated HbA1c test	BMI ≥ 30 or BP ≥ 140/90	All	All
Pre-screening scenarios targeting patients meeting the following additional criteria
Age 50 years or greater	All	All	All
BMI 30 kg/m2 or greater	All	All	All
Above median of diabetes and CVD risk	All	All	All
Top quartile of diabetes and CVD risk	All	All	All

In all cases, individuals had to be aged 40–75 and not have a previous diagnosis of diabetes, myocardial infarction, stroke, or serious chronic kidney disease to be eligible for a health check. In the pre-screening strategies, individuals also had to meet the additional criteria listed in the table. Eligible individuals received the health check at a 5 year interval in all strategies considered.

^*Eligible individuals were given an HbA1c test.

^†Diet and exercise for individuals with 6.0% ≤ HbA1c <6.0%, and smoking cessation interventions for smokers.
