Some data were wrong in this paper by Toby Lipman and Dawn Price (22 April, pp 1114-8). In table 3, under the heading “Organism” the correct number (percentage) for the 7 day treatment for “No growth” should have been 16/43 (37) [not 16/74 (22)] and that for “Trimethoprim sensitive” should have been 25/43 (58) [not 25/74 (34)].
