| Imaging Parameter (Unit) | Odds Ratioa | 95% Confidence Interval | P Valueb |
|---|---|---|---|
| Perifoveal leakage on FA (area %) | 1.064 | 1.007–1.124 | 0.027 |
| Parafoveal vessel density in SVP (%) | 1.039 | 0.872–1.238 | 0.669 |
| Parafoveal vessel density in DVP (%) | 0.957 | 0.828–1.105 | 0.549 |
| FD-300 (%) | 0.733 | 0.620–0.867 | <0.001 |
| FAZ area (mm2) | 0.055 | 0–14.844 | 0.310 |
| FAZ perimeter (mm) | 1.028 | 0.348–3.034 | 0.960 |
| FAZ a-circularity index | 16.748 | 0.300–935.863 | 0.170 |
a
Odds ratio represents the change in the risk of suboptimal clinical course if the value of imaging parameter rises by one numerical unit in that variable.
b
After adjusting for age, sex, and severity of diabetic retinopathy.
DVP, deep vascular plexus; FA, fluorescein angiography; FAZ, foveal avascular zone; FD-300, vessel density of the whole inner retinal layer within a width of 300 µm around the foveal avascular zone; SVP, superficial vascular plexus. Bold values indicate P < 0.05.
