A topic in Clinical Evidence summarizes the results of 9 RCTs, some with crossover design. 4 RCTs found that topical corticosteroids reduced the ulcer day index. The difference was significant in only two RCTs. Two out of six RCTs found that topical corticosteroids reduced ulcer duration or the total number of ulcer days. Three of four RCTs found that topical corticosteroids reduced pain. Clinical Evidence category: Unknown effectiveness.
Comment: The quality of evidence was downgraded by inconsistency of results.
