  • Characteristics of the entire Diabetes Watch Cohort were from the first systemic visit (and diabetic retinopathy screening episode, if retinopathy grade was available). The characteristics for the modelled cohort were from the index screening.

  • BMI, body mass index; BP, blood pressure; DW, Diabetes Watch; HDL, high-density lipoprotein; LDL, low-density lipoprotein; R0, no diabetic retinopathy on fundus images; R1M0, mild non-proliferative diabetic retinopathy and no maculopathy.
