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,

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.
