“…A manual review of complete reports eliminated 51 of them for the following reasons: administration path (7), review papers (4), pharmacokinetics studies (10) animal studies (9), indication (15), combined therapies (6), leading to the inclusion of the data of 14 studies (8,10,11,14,15,18,19,21,22,26–29). Four of them included naproxen as comparator (10,11,15,18), seven indomethacin (11,19,22,26–29), three aspirin (14,29), one ibuprofen (25) and one ketoprofen (8), accounting for a total of 1103 patient‐year. Four studies were multicentric (8,10,18,25).…”
