“…After removal of duplicates, 1976 citations were screened at the title and abstract stage and 79 eligible articles were identified. Thirty seven studies were excluded because the study design did not fit our criteria [ 12 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ]; a number of these studies assessed the anti-adhesion effects of urine obtained from healthy volunteers following cranberry consumption, when combined with uropathogen cultures ex vivo. Eleven studies were excluded as they did not assess UTI [ 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ,…”

“…One animal study was also excluded [ 81 ]. Eight studies were excluded as they were duplicates of five eligible studies [ 21 , 36 , 43 , 65 , 68 ]. After initially including seven studies, a further four were excluded; one was a duplicate [ 82 ], the author of a second study confirmed that they included patients with complicated UTI [ 83 ], one was a trial registration of an ongoing RCT [ 82 ] and one was a completed feasibility RCT with no published results [ 84 ].…”

Cranberries ( Vaccinium macrocarpon ) for urinary tract infections [44,45], mistletoe ( Viscum album ) for cancer [46-48], peppermint ( Mentha piperita ) oil for irritable bowel syndromes [49,50] and saw palmetto ( Serenoa repens ) for benign prostate hyperplasia [51-53] have each been subject to two reviews. For saw palmetto there is good evidence for efficacy over placebo while for the other three the data are inconclusive (see table 3).…”
