Correlation between plasma level of lipid components and VEGF with their levels in vitreous among HC and T2DM (subjects from DNR + MNPDR + HRPDR) group

Parameters	HC	T2DM
TL (mg/dl)	r = 0.35, p = 0.47	r = 0.76, p < 0.0001
FFA (mmol/L)	r = 0.21, p = 0.64	r = 0.67, p < 0.0001
MDA (µmol/L)	r = 0.31, p = 0.54	r = 0.84, p < 0.0001
HNE (pg/ml)	r = 0.32, p = 0.49	r = 0.79, p < 0.0001
HLY (nmol/L)	r = 0.29, p = 0.56	r = 0.73, p < 0.0001
VEGF (pg/L)	r = 0.28, p = 0.60	r = 0.72, p < 0.0001

The DNR, MNPDR and HRPDR groups are combined together and termed as Type 2 Diabetes Mellitus (T2DM) group. Pearson or Spearman's rank correlation coefficient (r) was used and a value of p < 0.05 was considered as statistically significant

TL, total lipid; FFA, free fatty acid; HNE, 4-Hydroxynonenal; MDA, malondialdehyde; HLY, hexanoyl-lysine; VEGF, vascular endothelial growth factor
