Exploring the Efficacy of Methenamine Hippurate Across Different Patient Groups With Recurrent Urinary Tract Infections: Experience From a University Teaching Hospital in South Wales, United Kingdom.

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
introductionRecurrent urinary tract infections (rUTIs) represent a significant clinical challenge, traditionally managed with long-term antibiotic prophylaxis. However, growing concerns regarding antimicrobial resistance have necessitated the exploration of alternative treatment modalities. Methenamine hippurate (MH), a urinary antiseptic with a unique mechanism of action, has emerged as a promising non-antibiotic option for rUTI prevention.
objectiveThis study aims to examine the effectiveness of MH in the prophylaxis of rUTI, with a specific focus on patients with structural or functional abnormalities of the urinary tract and those requiring catheterization to empty their bladder.
methodsA retrospective observational study was conducted on the first 150 patients prescribed MH in a University Hospital at a Local Health Board in South Wales from April 2020 to July 2022. Patient demographics, radiological findings, functional urological status, catheter use, and treatment outcomes were analyzed. Chi-square statistical tests were used to assess associations between categorical variables and treatment outcomes.
resultsThe cohort comprised 132 females (88%) with a median age of 60 years. After 12 weeks of treatment, 100 (66.7%) of patients showed improvement, with about half of these (n = 46) experiencing complete resolution of UTIs and a further third (n = 35) reporting reduced frequency or severity at six months follow-up. No statistically significant difference in long-term outcomes was observed based on radiological findings (χ
