The table of included participants provides a detailed census of the 3027 participants in 39 studies pooled in our inclusive analysis (Data synthesis/inclusive analysis). We provide a breakdown of the number of participants that contributed data at different follow‐up intervals. The first column lists the total number of participants pooled for each surgical subgroup; subsequent columns break the participants down by follow‐up interval. The last row sums participants at different follow‐ups. Most of the study data were observed at three and six months after surgery. If a study reported outcomes at more than one follow‐up, we counted the study data only once, at the last follow‐up reported for that study (Unit of analysis issues).
