- You are concerned that this association may be confounded by age so you decide to stratify your results by age, comparing individuals under 50 and those 50 and older. A total of 49 cases were younger than 50, and 30 of them were also obese. Among controls, 454 were younger than 50, and 200 of those were also obese. Among participants 50 and older, 20 cases and 78 controls were obese. Please calculate the odds ratios of CVD associated with obesity for both older and younger participants, and state the results of each in a sentence.
| Age <50 | CVD | No CVD | |
| Obese | |||
| Not obese | |||
| Age 50+ | CVD | No CVD | |
