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
The WRKY transcription factor is a key regulatory protein involved in defence hormone signalling and plays a pivotal role in plant hormone-mediated disease resistance. However, the specific mechanism by which WRKY transcription factors regulate the jasmonic acid (JA) pathway to confer resistance against Verticillium wilt in cotton remains poorly understood. In this study, we demonstrated that GbWRKY11 expression in Gossypium barbadense was induced by both Verticillium dahliae and methyl jasmonate (MeJA), and its encoded protein functioned as a nuclear transcription activator. Functional analyses revealed that GbWRKY11 enhances Verticillium wilt resistance by modulating JA pathway-related gene expression in both cotton and Arabidopsis. Exogenous MeJA application restored resistance in GbWRKY11-silenced plants, further supporting its role in JA-mediated immunity. Mechanistically, GbWRKY11 directly binds to the W-box motif in the promoter of GbLOX5, a key JA biosynthesis gene, and activates its transcription. Silencing GbLOX5 compromised cotton resistance to Verticillium wilt, confirming the importance of JA synthesis in this defence response. Our findings elucidate the molecular mechanism by which GbWRKY11 mediates immune responses against Verticillium wilt, providing novel insights into the genetic resources associated with disease resistance in G. barbadense.
