Thanks for looking at my question.

Background

I am doing a systematic reveiw and metanalysis, essentially on diagnostic test accuracy and particularly on the accuracy of 'tests' alone or in combination. Some studies do not report sensitivity and specificity or the % or no. of people with the symptom/s who have the disease/outcome or people with the symptom/s who don't have the disease/outcome. These studies report only the odds ratio i.e. the odds that people with the symptom will have the disease.

Question

Can I calculate the % or no. of people with symptom/s A who had the disease/outcome in a (published) study, and,

the % or no. of people who did not have symptom/s A who had the disease/outcome, if,

the only information I have is the odds ratio (95% CI and p value) and the total number of people in the study/including in the analysis?

If so I would really appreciate it if someone could tell me the formula or name of analysis in r/stats software.

Many thanks
