Summary of correlation coefficients (r) for retinal nerve fibre layer thickness (histological measurements) against retardation value for matched retinal locations.The definitions of the superior, inferior, nasal, and temporal sectors are described in Figure3
| Total | Temporal | Superior | Nasal | Inferior | |
|---|---|---|---|---|---|
| N | 216 | 86 | 26 | 59 | 45 |
| r | 0.7 | 0.48 | 0.52 | 0.062 | 0.76 |
| b | 14.02 | 22.61 | 10.75 | 1.61 | 20.85 |
| b0 | 15.82 | -19.91 | 29.41 | 71.67 | -41.86 |
| p | <0.001 | <0.001 | 0.007 | 0.64 | <0.001 |
-
N = number of pairs used to calculate the correlation coefficient in each sector. b = gradient of the straight line fitted to the data (μm/degree). b0 = intercept on the y axis (thickness, μm).
