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
backgroundThe sustainable control of weed populations is a significant challenge facing farmers around the world. Although various methods for the control of weeds exist, the use of small molecule herbicides remains the most effective and versatile approach. Striving to find novel herbicides that combat resistant weeds via the targeting of plant specific modes of action (MoAs), we further investigated the bicyclic class of acyl-acyl carrier protein (ACP) thioesterase (FAT) inhibitors in an effort to find safe and efficacious lead candidates.
resultsUtilizing scaffold hopping and bioisosteric replacements strategies, we explored new bicyclic inhibitors of FAT. Amongst the investigated compounds we identified new structural motifs that showed promising target affinity coupled with good in vivo efficacy against commercially important weed species. We further studied the structure-activity relationship (SAR) of the novel dihydropyranopyridine structural class which showed promise as a new type of FAT inhibiting herbicides.
conclusionThe current work presents how scaffold hopping approaches can be implemented to successfully find novel and efficacious herbicidal structures that can be further optimized for potential use in sustainable agricultural practices. The identified dihydropyranopyridine bicyclic class of herbicides were demonstrated to have in vitro inhibitory activity against the plant specific MoA FAT as well as showing promising control of a variety of weed species, particularly grass weeds in greenhouse trials on levels competitive with commercial standards. © 2024 The Author(s).
