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
O-methyltransferases (OMTs) are a group of enzymes involved in several fundamental biological processes in plants, including lignin biosynthesis, pigmentation, and aroma production. Despite the intensive investigation of the role of OMTs in plant secondary metabolism, the evolution and diversification of this gene family in Solanaceae remain poorly understood. Here, we conducted a genome-wide survey of OMT genes in six Solanaceae species, reconstructing gene phylogenetic trees, predicting the potential involvement in biological processes, and investigating the exon/intron structure and chromosomal location. We identified 57 caffeoyl-CoA OMTs (CCoAOMTs) and 196 caffeic acid OMTs (COMTs) in the studied species. We observed a conserved gene block on chromosome 2 that consisted of tandem duplicated copies of OMT genes. Our results suggest that the expansion of the OMT gene family in Solanaceae was driven by whole genome duplication, segmental duplication, and tandem duplication, with multiple genes being retained by neofunctionalization and subfunctionalization. This study represents an essential first step in unraveling the evolutionary history of OMTs in Solanaceae. Our findings deepen our understanding of the crucial role of OMTs in several biological processes and highlight their significance as potential biotechnological targets.
