Hazard of developing VTDR for known risk factors from multivariate Cox regression analysis

	HR	95% CI	p‐value
Mean HbA1c (mmol/mol)	1.023	1.011–1.036	<0.001
Albuminuria	2.940	1.130–7.648	0.028

HR = hazard ratio; 95% CI = 95% confidence interval.

The hazard ratio for continuous variables should be interpreted as hazard per point of increase in the variable per time unit. For example, when the HbA1c level increases with 10 points, the instantaneous risk of DR progression is 1.024¹⁰ = 1.268 or 26.8% higher.
