Stratified by ETDRS grade*
No DR (n=1719)0.00.01.01.4
Mild NPDR (n=1034)2.24.810.713.4
Moderate NPDR (n=1527)5.611.823.929.5
Severe NPDR (n=165)12.626.746.059.0

  • *Stratification is by ETDRS grading of retinopathy at most recent assessment prior to cataract surgery (mild, moderate and severe NPDR and PDR retinopathy). See previous table legend regarding upper boundaries of time periods.

  • NPDR, non-proliferative diabetic retinopathy; PDR, proliferative diabetic retinopathy.
