Basically I`ve done a review of the literature on disengagement from Early Intervention Psychosis services using systematic methods. There was heterogeneity across the studies, no RCTs and I`ve used `vote counting` to make sense of the results
According to Cochrane's handbook, there are two main concerns about using vote counting to make sense of results: by considering each study on its own you are not allocating different weight to them, and too much emphasis is given to significant/not-significant, without considering range of effects (e.g., CI) (https://handbook-5-1.cochrane.org/chapter_9/9_4_11_use_of_vote_counting_for_meta_analysis.htm)
