I want to compare how does use of drug "A" differs across age categories.
Total drug A users were 5100. The below table shows the number and percentage of users for each age category. I want to compare whether there is any difference in the use of drug A with regards to age? Do people younger than 49 years old have a significant drug use than people 65 years or older?
| <49 | 1794/5100 (35.2%) |
| 50-64 | 1102/5100 (21.6%) |
| ≥65 | 1242/5100 (24.4%) |
| Missing | 30/5100 (0.1%) |
I'm not sure about the stata command to compare more than two categories. I would highly appreciate your thoughts!
Thank you in advance!
