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
objectiveThis study investigates antibiotic resistance patterns, virulence factors, and phylogenetic groups of O25 and O16 serogroups in uropathogenic Escherichia coli (UPEC) isolates from kidney transplant recipients (KTPs) and non-KTPs. The presence of serogroups O25 and O16, resistance genes (e.g., bla
resultsA total of 111 E. coli isolates were examined in the present study. The O-serotyping results indicated that 18% and 3.6% of isolates were positive for O25 and O16 serogroup, respectively. In serogroup O25, the highest resistance rates were observed for nalidixic acid and cotrimoxazole, whereas in serogroup O16, the highest resistance rates were against cotrimoxazole and ampicillin-sulbactam. ESBL production was identified in 30% of O25 and 25% of O16 isolates. O25 isolates belonged to phylogenetic group B2, whereas O16 isolates were grouped in B1. ERIC-PCR revealed significant genetic diversity among isolates. The O25 serogroup is prevalent and closely associated with high antibiotic resistance and virulence, suggesting its critical role in UTI pathogenesis in transplant patients. These findings underscore the importance of monitoring resistance patterns and developing targeted therapeutic and preventive strategies for managing UPEC infections.
