Show Suggested Answer

Suggested Answer: D

Odds ratio of 0.44 (44%) means that this group was associated with an event happening 44% of the time, compared to 1 (an event happening 100% of the time if unexposed), therefore 100 - 44 = 56%, which is the reduction caused by the exposure. Exposure is the use of ascorbic acid.
