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
backgroundBloodstream infections remain a major cause of morbidity and mortality worldwide, with the increasing threat of antimicrobial resistance (AMR) complicating treatment options. This study aimed to describe the frequency, distribution, and patterns of AMR among blood culture isolates over 5 years at the University Teaching Hospital of Kigali, in Rwanda.
methodsA retrospective cross-sectional surveillance analysis was performed on 1352 bacterial isolates from 8301 blood cultures conducted between January 1, 2020, and December 31, 2024. The distribution of pathogens, antimicrobial resistance profiles, and comparisons of resistance patterns between isolates from outpatient and hospitalized patients were analyzed using SPSS version 28. A p-value less than 0.05 was considered statistically significant.
resultsThe most common isolates were Staphylococcus aureus (37.2%), Klebsiella pneumoniae (22.4%), Escherichia coli (13%), and Acinetobacter baumannii (11.6%). Nearly all isolates originated from inpatients (98.6%), with the pediatric unit accounting for 40.7%. Alarmingly high resistance rates were observed for ampicillin (94.2%), amoxicillin-clavulanic acid (92.5%), third-generation cephalosporins (79-86%), and ciprofloxacin (58.7%). Notably, vancomycin (1%) for Gram-positive bacteria, and polymyxin B (27.1%), imipenem (25.5%), and amikacin (15.6%) for Gram-negative bacteria generally exhibited lower resistance rates. Additionally, AMR was significantly more prevalent in isolates from hospitalized patients compared to ambulatory patients (p < 0.0001).
conclusionThis study reveals a substantial burden of AMR in blood culture isolates, particularly affecting hospitalized and pediatric patients. The high resistance rates to commonly used antibiotics highlight an urgent need for strengthened antimicrobial stewardship programs, improved infection prevention measures, and enhanced diagnostic laboratory capacity to guide therapy.
