Analysis of Infection Types, Pathogens, Antimicrobial Treatment, and Clinical Outcomes Data in Hospitalised Patients: Comprehensive Online Database for Antimicrobial Resistance (CODAR) Retrospective Pilot Study.
Article in Journal of epidemiology and global health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEffective surveillance of prevalent infections, pathogen distribution, and treatment patterns help inform patient management and enhance outcomes. The Comprehensive Online Database for Antimicrobial Resistance (CODAR) pilot study aimed to provide insights into epidemiology, existing treatment strategies, and outcomes.
methodsThis surveillance study (February 2023-2024) across 21 hospitals in India, Mexico, Saudi Arabia, Spain, and the United Kingdom (UK) evaluated pathogen distribution, antimicrobial treatments, and survival rates in hospitalised patients using electronic health records and hospital reports.
resultsAmong 8060 eligible patient records, 7434 (92.2%) with complete data were included in this analysis. Urinary tract infections (UTI), predominantly occurring in female patients (59.0%), were the most prevalent across countries (29.0%). Comorbidities such as vascular and metabolic and nutritional disorders were most commonly observed across countries included in this study. Meropenem and amoxicillin-clavulanate were most commonly used antimicrobials in India and the UK, respectively, across most infection types. Patients with skin and skin structure infections had the highest survival rates (94.4%) and shortest hospital stay (mean [standard deviation], 20.6 [33.53] days), whereas those with bloodstream infections (BSI, 81.7%), mixed infections (82.1%), and lower respiratory tract infections (LRTI, 83.3%) had relatively lower survival rates. Low proportion of patients alive (≤55.0%) with both monotherapy and combination therapy were observed with Acinetobacter baumannii (LRTI), Klebsiella pneumoniae (LRTI and BSI), and Escherichia coli (UTI) in India and Staphylococcus aureus (SSSI) and Enterococcus faecium (UTI) in the UK.
conclusionLow survival rates associated with infections caused by specific pathogens highlight challenges in managing these infections, necessitating ongoing surveillance for effective infection control with suitable antimicrobial therapies to enhance patient care.
