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
Numerous Gram-negative bacteria possess N-acyl-L-homoserine lactone (AHL)-mediated quorum-sensing (QS) systems that regulate the activation of specific genes. Burkholderia plantarii causes rice seedling blight by producing the phytotoxin tropolone. In this study, we investigated multiple AHL-type QS systems in B. plantarii MAFF 301723T and their involvement in virulence regulation. MAFF 301723 harbors three AHL-mediated QS systems, designated plaI1/plaR1, plaI2/plaR2, and plaI3/plaR3. The plaI1/plaR1 system, which produces N-octanoyl-l-homoserine lactone, is functional and essential for swarming motility. When forced expression of plaI2 induces the biosynthesis of 3-OH-C10-HSL, it was suggested that expression is rarely observed in wild-type MAFF 301723. The plaI3 gene directs the synthesis of the putative C16:2-HSL, which is a rare AHL bearing two double bonds in the hexadecanoyl chain that has not been previously reported in Burkholderia spp. The plaI3/plaR3-QS system is crucial for tropolone production. These findings suggest that multiple QS systems collectively contribute to the complex virulence regulation of B. plantarii, thereby providing new insights into the development of QS-targeted biocontrol strategies for agriculture.
