Hi, all,
I'm checking the increase rates of outpatient visits for certain diseases on the same sample. As you see,
The number of outpatient visits all increased after a time point. Among them, Disease1 had the highest increase rates(50%)
Is there any way to do a statistical analysis to compare the increase rates of ‘disease1’ 50% to that of 'total diseases' 27%? The sample is non-independent. I appreciate for any suggestion.
| before | after | Increase rates |
Number of visits on Disease1 | 100 | 150 | 50% |
Number of visits on Disease2 | 100 | 120 | 20% |
Number of visits on Disease3 | 100 | 110 | 10% |
All diseases | 300 | 380 | 27% |
