a
1 point for attainment of ICH and 0 points for intermediate or poor cardiovascular health per category were summed to create a total score ranging from 0 to 6 and categorised into poor (0-1 ICH components), intermediate (2-3 ICH components) and ideal (≥4 ICH components)
b
Unable to define incident diabetes rate due to lack of participants meeting criteria for the category NA, not applicable
