Hello all, this seems like it should be a simple questions but our team cannot find an answer to the question. If I have data set up like the following (the numbers are the percent that react positively to the drug):

and my goal is to see whether there is a significant difference in the observed trends in rates over time. How can I test this...unfortunately in my line of work, this is all we get, we cannot get data with the sample sizes or any other information. Any help would be greatly appreciated as I have ran into this problem many times.

Thank you so much!

Code:

```
Drug 2007 2008 2009 2010
A 59 62 61 62
B 50 49 58 61
C 67 70 69 83
```

Thank you so much!
