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
UDP-glycosyltransferases (UGTs) were widely distributed in plants and played crucial roles in mediating glycosylation reactions associated with metabolic pathways. Although the UGT gene family has been characterized in numerous plant species, a systematic analysis in Populus trichocarpa still requires further refinement. In this study, 204 PtrUGT genes were identified through genome-wide analysis, revealing significant variations in protein length, molecular weight, and isoelectric point. Chromosomal mapping revealed an uneven distribution across all 19 chromosomes, with chr16 exhibiting the highest gene density. Furthermore, tandem duplication events were identified as the primary drivers of gene family expansion. Synteny analysis of P. trichocarpa identified 266 paralogous PtrUGT gene pairs, with significant enrichment on Chr16, which were highly conserved among closely related woody plants. Phylogenetic classification grouped the PtrUGTs into 19 distinct subgroups (A-S), with subgroup-specific motif conservation and gene structures. Promoter analysis uncovered abundant cis-regulatory elements associated with light, methyl jasmonate, abscisic acid, and stress responses, indicating functional diversification among the PtrUGT genes. Both RNA-seq and quantitative real-time PCR (qRT-PCR) analyses revealed tissue-specific expression patterns and stress-responsive regulation, with certain PtrUGTs showing significant induction under drought, salt stress, or insect herbivory stress. Subcellular localization analysis revealed that the stress-responsive PtrUGT198 was present in both the nucleus and the cytoplasm. This study provides a systematic characterization of the PtrUGT family, offering valuable insights for identifying genes related to stress resistance and facilitating molecular breeding strategies in poplar.
