The references were a couple of sentences before. Miller et al. 2004, "Meta-Analysis: High-Dosage Vitamin E Supplementation May Increase All-Cause Mortality", "Randomized Trial of Vitamin A and Vitamin E Supplementation for Retinitis Pigmentosa." Though I see the formatting made it look like 1 reference instead of 2, and the link was broken.

Also, this is something you can easily google if you question it.

People familiar with vitamin studies would know right away that 200,000IU of vitamin A and 5,000IU of vitamin E per day are both extremely high, and not in the same category as "vitamin supplementation".
