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.

2 · The registry

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 bacterial infections worldwide, and increasing multidrug resistance (MDR) and extended-spectrum β-lactamase (ESBL) production among uropathogenic Enterobacterales have increasingly limited empirical and targeted treatment options, particularly in low- and middle-income countries. Methods: This laboratory-based cross-sectional study was conducted at Bangladesh Medical University, Dhaka, Bangladesh. Eligible MDR uropathogenic Enterobacterales isolates from routine diagnostic urine specimens were collected and tested after Institutional Review Board approval on 13 July 2025. Urine specimens were obtained as part of standard hospital diagnostic procedures from patients with suspected UTI. A total of 122 MDR isolates were included. Bacterial identification was performed using conventional biochemical methods. Antimicrobial susceptibility testing was performed by Kirby-Bauer disk diffusion following CLSI 2024 guidelines, and phenotypic ESBL production was detected by the double-disc synergy test. MDR classification was based on the complete routine antimicrobial susceptibility testing record, including amikacin and gentamicin. Descriptive statistics and exact binomial 95% confidence intervals (CIs) were calculated. Results: Among these 122 MDR isolates, Conclusion: Among MDR uropathogenic Enterobacterales from a single tertiary-care hospital in Bangladesh, ciprofloxacin and cephalosporin resistance and phenotypic ESBL production were high. Findings support routine ESBL screening, local susceptibility surveillance, and antimicrobial stewardship, but should be interpreted within the study's MDR-only, single-center scope.
