Stepwise multiple regression analysis by the forward method of quality of life score (dependent variable Y) in relation to vision test scores and age (independent variables X1 to X6) in 132 patients with uveitis
| X selected | R | R2 | F | SSEx |
|---|---|---|---|---|
| Independent variables: high contrast visual acuity best eye (X1), high contrast visual acuity worst eye (X2), binocular high contrast visual acuity (HCVA binocular, X3), binocular low contrast visual acuity (X4), binocular contrast sensitivity (X5), and age (X6). | ||||
| R = multiple regression coefficient, F = variance ratio, SSEx = percentage of the variance in Y associated with or explained by each X variable; *p<0.01, **p<0.001. | ||||
| HCVA binocular | 0.28 | 0.08 | 11.24* | 8% |
| Age | 0.39 | 0.15 | 11.98** | 7% |
