	CLVR (n = 76)		ELVR (n = 75)		CELVR (n = 75)
	Median (n)	Q1–Q3 (%)	Median (n)	Q1–Q3 (%)	Median (n)	Q1–Q3 (%)
Age (years)	81	77–84	80	76–85	83	78–86

Registered as blind or partially sighted:

Distance visual acuity (logMAR)†	0.81	0.48–1.00	0.90	0.56–1.08	0.62	0.44–1.00
Continuous text reading acuity (M units)‡	2.00	1.15–4.00	2.50	1.00–5.00	1.60	1.00–2.50
Pelli-Robson contrast sensitivity§	0.90	0.60–1.05	0.83	0.45–1.05	1.00	0.60–1.05

†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.
