A randomized, triple-blind, placebo-controlled, parallel study of the efficacy of D-mannose for urinary tract infection symptoms in women.
Article in Current urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Urinary tract infections (UTIs) are common infectious disorders affecting 50% of healthy women at least once during their lifetime. Antibiotic treatment for UTIs may increase the prevalence of antimicrobial resistance and side effects, highlighting the need for safe and efficacious alternatives. This study investigated the effect of acute supplementation with UClear, a D-mannose product, on UTI symptoms. Materials and methods: Women with at least 2 uncomplicated UTI symptoms, as assessed using the UTI Symptom Assessment (UTISA) questionnaire and urine nitrite and leukocyte testing, were randomized to receive UClear or a placebo for 3 days. The study outcomes included changes in the UTI symptom severity and bother scores, complete resolution of UTI symptoms, urine culture data, quality of life assessed using the RAND 36-Item Short Form Survey questionnaire, and rescue medication use. Study outcomes were measured from baseline to days 2, 3, and 4. Results: The total UTISA severity scores were not significantly different between the groups. Participants supplemented with UClear had lower total UTISA bother scores after 3 days than the placebo group ( Conclusions: After 3 days of UClear supplementation, urination-related UTI symptoms improved compared with those of the placebo group. These improvements corresponded with significant improvements in the degree of discomfort due to those symptoms. Further investigations in at-risk populations are warranted to understand the efficacy of UClear in resolving UTIs.
