1 · What the graph read from it

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.

Abstract

backgroundUrinary tract infection (UTI) is one of the most common bacterial infections, contributing to increased antibiotic consumption and high healthcare costs. Clinical studies suggest that probiotics can be effective dietary supplements reducing the risk factors for the development of infections in the intestine and vagina. In this study, we investigate the effect of the orally ingested probiotic combination ASTARTE™ on the composition of bacteria in vaginal and fecal samples, as well as on the occurrence of bacteriologically confirmed UTIs in women of reproductive age.

methodsA randomized, placebo-controlled, double-blind study evaluating the effect of the probiotic combination ASTARTE™ (Chr. Hansen A/S, Part of Novonesis Group, Denmark) on reducing the number of recurrent urinary tract infections (rUTIs) in women aged 18-40 years. Participants are randomized (1:1) to receive one daily probiotic capsule (5 × 10 DISCUSSION: This randomized, placebo-controlled, double-blind study investigates the effectiveness of ASTARTE™ in restoring beneficial microbiomes and reducing UTI recurrence. The findings will provide valuable evidence on the effectiveness of a non-antibiotic strategy for the prevention of rUTI as well as insights into the complex interactions between the vaginal and gut microbiome and the risk of rUTI.
