Results from a Meta-analysis where they looked at frequency of postoperative arterial fibrillation in patients on Ascorbic acid after cardiac surgery found odds ratio, 0.44 (95% CI, 0.32 to 0.61). How can you interpret this data?

AAscorbic acid increased frequency of postoperative arterial fibrillation after cardiac surgery by 44%

BAscorbic acid decreased frequency of postoperative arterial fibrillation after cardiac surgery by 44%

CThere was no statistically significant difference in frequency of postoperative arterial fibrillation after cardiac surgery

DAscorbic acid decreased frequency of postoperative arterial fibrillation after cardiac surgery by 56%

ENone of the above are correct

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.
