Most procedures I found use only one proportion per study. But all the studies I am analyzing have within-subject designs. They compare the proportion of successes in the manipulation with the proportion of successes in the control condition. All sample sizes are known.
The meta-analysis method for dichotomous models asks me for sample sizes of two groups, but that does not make sense for within designs, right? The same people performed the manipulation and the control condition.
What is the appropriate procedure to conduct a meta-analysis with within designs that compare conditions and have proportion as data?
