Correlation coefficients from multivariate regression analysis with Rasch‐estimated person measures
| Reference | Adjusted r 2 | p‐value | |
|---|---|---|---|
| Model summary | 0.388 | <0.001 | |
| Age | Per year | 0.903 | |
| Gender | Male | 0.115 | |
| VFIa in eye with better VF | Per % | <0.001 | |
| VA in eye with better VA | Per 0.1 unit on Snellen scale | <0.001 |
VA = visual acuity, VF = visual field.

Mean deviation value was not included in the multivariate model, because the visual field index (VFI) showed higher correlation with Rasch person measures in univariate analysis.
