Demographic and visual function characteristics of participants at baseline

|---|---|---|---|---|---|---|
| Median (n) | Q1–Q3 (%) | Median (n) | Q1–Q3 (%) | Median (n) | Q1–Q3 (%) | |
| †Distance visual acuity data were missing for four patients allocated to CLVR, two allocated to ELVR, and four allocated to CELVR. | ||||||
| ‡Continuous text reading acuity data were missing for three patients allocated to CLVR, seven allocated to ELVR, and six allocated to CELVR. | ||||||
| §Contrast sensitivity data were missing for 20 patients allocated to CLVR, 17 allocated to ELVR, and 14 allocated to CELVR. | ||||||
| Data were missing because optometrists carrying out the low vision assessments sometimes failed to obtain or record the information, not because patients refused or were unable to perform the task. | ||||||
