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
Enterobacterales such as Escherichia coli are known to produce extended-spectrum β-lactamase (ESBL) enzymes at high rates in Ghana, West Africa. However, little is known about the One Health connections that may facilitate the dissemination of these resistant bacteria. This study aimed to use whole-genome sequencing (WGS) to investigate resistance determinants, virulence genes, and associated mobile genetic elements (MGEs) of ESBL-producing E. coli isolated from stool samples of Ghanaian children under five years of age, both with and without diarrhoea, and from farm animals, including poultry and goats.A total of 117 confirmed ESBL-positive E. coli isolates recovered from stool samples of children without diarrhoea (44/117), children with diarrhoea (30/117), poultry (35/117), and goats (8/117) were subjected to WGS. Phylogenetic analyses based on multilocus sequence typing (MLST) identified 49 distinct sequence types (STs), with ST617 and ST38 among the most prevalent lineages. ESBL production was predominantly mediated by the blaCTX−M−15 gene. Overlapping resistant genes and ST profiles observed between human and animal isolates suggest shared reservoirs. In summary, the work provides region-specific genomic evidence of shared sequence types, resistance genes, virulence factors, and mobile genetic elements among ESBL-producing E. coli isolates from children and farm animals in Ghana. These findings highlight the potential dissemination of multidrug-resistant strains and fill an important knowledge gap within a One Health context. Thus, the study provides a region-specific baseline for future molecular epidemiological surveillance and One Health–focused investigations in Ghana.
