| Independent variables | Coefficient | p Value | 95% Confidence intervals |
|---|---|---|---|
| Age (years) | −0.0046 | <0.001 | (−0.006, −0.003) |
| Sex | 0.170 | <0.001 | (0.131, 0.21) |
| IOP (mm Hg) | −0.027 | <0.001 | (−0.032, −0.022) |
| Refraction (D) | 0.049 | <0.001 | (0.041, 0.058) |
| Pulse rate (beats/min) | 0.0038 | <0.001 | (0.002, 0.005) |
| NTG eyes normal field | −0.099 | 0.007 | (−0.17, −0.027) |
Independent variables age, IOP, refraction, and pulse rate were introduced as continuous. Sex was analysed as categorical variable, 1 = male; 2 = female. NTG was introduced as dichotomous variable; 0 = normal, 1 = NTG. Adjusted r 2 = 0.291, residual SD = 0.007.
