Gene Expression of IGF1, IGF1R, and IGFBP3 in Epiretinal Membranes of Patients with Proliferative Diabetic Retinopathy: Preliminary Study

Table 3

The correlations between relative expression of IGF1, IGF1R, and IGFBP3 and time interval between diagnosis and surgery in the ERMs and PBMCs of diabetic and nondiabetic patients.

Diabetic patients
ERMs	IGF1	IGF1R	PBMCs	IGF1	IGF1R	IGFBP3
Time interval between diagnosis and surgery	𝑟=0.316	𝑟=−0.316	Time interval between diagnosis and surgery	𝑟=0.462	𝑟=0.103	𝑟=−0.462
Nondiabetic patients
iERMs	IGF1	IGF1R	PBMCs	IGF1	IGF1R	IGFBP3
Time interval between diagnosis and surgery	𝑟=0.065	𝑟=0.497	Time interval between diagnosis and surgery	𝑟=0.153	𝑟=0.470	𝑟=−0.442
