Which statistical test?

There are 16 previous studies and these are the results:

1. The cats’ performance was better than dogs: 7 studies.

2. There was no significant difference: 9 studies.

3. The dogs’ performance was better than cats: 0 study

Which statistical test is appropriate for analyzing this data? (If you have seen a study like this please notify me)

Thank you in advance for your help,



Less is more. Stay pure. Stay poor.
If you are referring to pooling these results, this would fall under "meta-analysis". Though, most times they are much more sophisticated than just averaging results.
