Topographic analysis of macular choriocapillaris flow deficits in diabetic retinopathy using swept–source optical coherence tomography angiography

Table 2 GEE results for the effect and significance of age and DR severity on FD % in the regions studied

Region	Age coefficient (std error)	P value	DR severity coefficient (std error)	P value	α correlation
Inner	0.12 (0.03)	< 0.001	0.65 (0.25)	0.0087	0.29
Middle	0.09 (0.02)	< 0.001	0.56 (0.17)	0.0012	0.29
Outer	0.05 (0.01)	< 0.001	0.33 (0.11)	0.0045	0.35
Full	0.06 (0.01)	< 0.001	0.36 (0.12)	0.0018	0.32

Coefficient is the average increase in FD % for a one unit increase in the covariate (age or DR severity) while controlling for other covariates. The α correlation values are non-zero, showing correlation between eyes of the same subject
