Hazard ratios for coronary heart disease by clinically defined categories of baseline fasting blood glucose concentration. Reproduced with permission.²³ Analyses were based on 279 290 participants (14 814 cases). Hazard ratios were adjusted as described in Figure 1. The hazard ratio in those with fasting plasma glucose 5.60–6.99 mmol/L was 1.12 (95% confidence interval 1.06–1.18). CI = confidence interval; HR = hazard ratio. aReference group.
