Retinal artery occlusion does not act as an independent marker of upcoming dementia: results from a Danish 20-year cohort study

Table 2 Hazard Ratio and 95% Confidence Interval for dementia according to retinal artery occlusion status

Number of events, incident rates and hazard ratios for incident dementia for patients with and without exposure
PYR, person-years at risk; IR, incidence rate; HR, hazard ratio; CI, confidence interval
*Per 1000 person-years
