Fig. 1. — Flow diagram of included studies in review and excluded studies. A total of 1,293 articles were found through electronic databases; however, 50 studies were duplicate findings. Among 1,243 studies, we regarded 1,214 articles as irrelevant after screening the title and abstract. Thirteen studies could not be retrieved. We reviewed the full texts of the remaining 16 articles and excluded eight irrelevant studies. Finally, a total of eight RCTs were included in the meta-analysis. NSAIDs: non-steroidal anti-inflammatory drugs, RCT: randomized controlled trial.
