I am doing a meta-analysis using the Open Meta software. The findings being meta-analyzed are simply the proportion of those with disease X who also have disease Y for each study. I am given an estimate of the overall proportion, the lower and upper bounds of the CI, and the significance value. I am not really sure how to interpret the significance value in this case. I have attached a photo.
The only thing it can be testing is whether the estimated proportion could be zero which it clearly is not. Whether that hypothesis makes any sense in your scientific situation is up to you but I would have thought it rarely, if ever, does.
If the documentation for this program is so poor that it does not tell you I would suggest you change to another program as it does not seem state of the art.
