Figure 1

Scatterplot and linear regression model showing correlation between age and pattern electroretinogram (PERG) N95 amplitude. Full-field (FF) PERG N95 amplitude was negatively correlated with age, with a regression coefficient of − 0.460 (β =  − 0.081, P < 0.001, (A)) in the entire study participants and also negatively correlated with age in the control and preperimetric glaucoma (PPG) groups (β =  − 0.065, P = 0.021, (B); β =  − 0.114, P = 0.001, (C), respectively). In contrast, the smaller/larger hemifield (HF) N95 amplitude ratio showed no correlation with age for the entire participants (β =  − 0.005, P = 0.195, (D)), the control group (β = 0.001, P = 0.980, (E)) or the PPG group (β =  − 0.008, P = 0.199, (F)).
