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
Pathogenicity islands (PAIs) play an important role in Shiga toxin-producing Escherichia coli (STEC) pathogenicity. The distribution of PAIs OI-122, OI-43/48, and OI-57 and a high-pathogenicity island (HPI) were determined among 98 STEC strains assigned to seropathotypes (SPTs) A to E. PCR and PCR-restriction fragment length polymorphism assays were used to identify 14 virulence genes that belonged to the four PAIs and to subtype eae and stx genes, respectively. Phylogenetic trees were constructed based on the sequences of pagC among 34 STEC strains and iha among 67 diverse pathogenic E. coli, respectively. Statistical analysis demonstrated that the prevalences of OI-122 (55.82%) and OI-57 (82.35%) were significantly greater in SPTs (i.e., SPTs A, B, and C) that are frequently associated with severe disease than in other SPTs. terC (62.5%) and ureC (62.5%) in OI-43/48 were also significantly more prevalent in SPTs A, B, and C than in SPTs D and E. In addition, OI-122, OI-57, and OI-43/48 and their associated virulence genes (except iha) were found to be primarily associated with eae-positive STEC, whereas HPI occurred independently of the eae presence. The strong association of OI-122, OI-43/48, and OI-57 with eae-positive STEC suggests in part that different pathogenic mechanisms exist between eae-positive and eae-negative STEC strains. Virulence genes in PAIs that are associated with severe diseases can be used as potential markers to aid in identifying highly virulent STEC.
