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
introductionIn Bangladesh, the antibiotic resistance patterns of uropathogens in patients with complicated urinary tract infections (cUTIs) remain poorly understood. This study aimed to identify the most prevalent bacteria in urine samples from cUTI patients and assess their resistance to commonly used antibiotics.
methodBetween January 2023 and June 2024, we conducted this retrospective cross-sectional study among patients from the Nephrology department of Bangladesh Medical College Hospital, Dhaka. Clinical and microbiological data were retrieved for adult patients with culture-confirmed UTI (≥ 10⁵ CFU/mL). Reports from patients with at least one documented complicating factor were included in the analysis. The antibiotic susceptibility of 31 commonly used antibiotics was evaluated using the standard Kirby-Bauer method. Descriptive statistics were used to summarize bacterial isolates, patient demographics, complicating factors, and antibiotic sensitivity patterns. Inferential tests were performed to assess associations between risk factors and specific pathogens.
resultsA total of 170 urine culture-positive samples from eligible patients were included in this study. E. coli was the most prevalent pathogen (49%) observed, followed by K. pneumoniae (25%) and P. aeruginosa (10%). Female patients accounted for 65% of cases. Diabetes mellitus (66%) was the most prevalent complicating factor, along with the presence of renal stone (16%) and an indwelling urinary catheter (11%). P. aeruginosa was significantly more common in diabetic and transplant patients. Antibiotic susceptibility testing revealed high resistance among E. coli and K. pneumoniae to Quinolones (10–55%) and Cephalosporins (4–55%). In contrast, P. aeruginosa showed significant resistance to aminoglycosides (31–63%) and Carbapenems (0–38%).
conclusionThis study demonstrates that E. coli and K. pneumoniae are the predominant uropathogens in patients with cUTIs in Bangladesh. Both organisms exhibited notable resistance to Quinolones and the Cephalosporins group of antibiotics. These findings underscore the need for tailored antibiotic stewardship programs to guide appropriate treatment decisions and improve clinical outcomes in cUTI patients.
