The hazard ratio (95% CI) for incident dementia associated with zinc supplementation was 0.84 (0.74\u20130.96), and the association remained significant after adjusting for all confounders (0.84 (0.74\u20130.96)). In the full model, zinc supplementation was associated with a reduced risk of Alzheimer\u2019s disease [HR (95% CI): 0.71 (0.57\u20130.88)]. There was no significant association between zinc supplementation and the risk of vascular dementia. No significant associations with incident dementia were observed for other antioxidant supplementation. The association between zinc supplementation and incident dementia was significant among individuals with [HR (95% CI): 0.34 (0.15\u20130.77)] and without cataract [0.87 (0.77\u20130.99)] but it was
