Retinal Vessel Diameters and Their Relationship with Cardiovascular Risk and All-Cause Mortality in the Inter99 Eye Study: A 15-Year Follow-Up

Table 4

Hazard ratios for all-cause mortality in relation to retinal vessel diameters.

(a)

By tertiles (ranges in μm)	Total number	Central retinal artery equivalent diameter (CRAE), µm
	Number of participants who died	Model 1: hazard ratio (95% CI)	value	Model 2: hazard ratio (95% CI)	value
1st ≤ 156.6	21	1.0 (reference)		1.0 (reference)
2nd 156.6–169.8	25	1.39 (0.7 to 2.5)	0.280	1.34 (0.7 to 2.4)	0.338
3rd ≥ 169.8	15	0.86 (0.4 to 1.7)	0.680	0.75 (0.3 to 1.5)	0.431

(b)

		Central retinal vein equivalent diameter (CRVE), µm
1st ≤ 242.0	14	1.0 (reference)		1.0 (reference)
2nd 242.0–260.2	21	1.50 (0.7 to 2.9)	0.245	1.35 (0.6 to 2.6)	0.390
3rd ≥ 260.2	26	2.02 (1.0 to 3.8)	0.033	1.34 (0.6 to 2.6)	0.392
