Differences in the overall visual functioning score by severity of age-related macular degeneration (AMD) in linear regression models
| Model 1 | Model 2 | Model 3 | Model 4 | |
| Mean (95% CI)* | Mean (95% CI)* | Mean (95% CI)† | Mean (95% CI)† | |
| No AMD (reference) | 89.7 (88.7 to 90.6) | 90.1 (89.3 to 91.0) | ||
| Early AMD | 0.13 (−1.9 to 2.2) | −0.45 (−2.4 to 1.5) | ||
| Late AMD | −6.4 (−11.7 to −2.1) | −0.55 (−5.8 to 4.7) | ||
| No/early AMD (reference) | 89.7 (88.7 to 90.6) | 90.1 (89.3 to 91.0) | ||
| Late AMD | −6.4 (−11.7 to −2.1) | −0.51 (−5.8 to 4.7) |
Adjusted means (SE) are given for the reference categories and β (β coefficients) (CI values for others). Bold coefficients represent independent variables significantly associated with vision-specific functioning (p<0.05).
