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
Background: Lipoxygenases (LOXs) catalyze polyunsaturated fatty acid oxygenation and regulate plant stress responses and oxylipin biosynthesis. This study provides comprehensive genome-wide characterization of the soybean LOX gene family, revealing unprecedented expansion and functional diversification. Methods: We identified unique Results: Genes distribute unevenly across 10 chromosomes, with highest densities on Gm10 (11 genes), Gm08 (9 genes), and Gm07 (8 genes). Phylogenetic analysis revealed six evolutionary clades with soybean-specific expansion. Structural analysis showed 92% encode full-length proteins (average 887 amino acids) with conserved PLAT/LH2 (97%) and catalytic domains. Promoter analysis identified 23 regulatory element categories, including hormone-responsive (auxin 97%, gibberellin 89%, ABA 94%), stress-responsive (95%), and light-responsive elements (100%). Synteny analysis demonstrated ancient whole-genome duplications and recent tandem duplications drove expansion. Expression profiling revealed five functional categories: alkaline-specific, drought-dominant, heat-specific, salt-responsive, and multi-stress responsive genes. Conclusion: Soybean possesses the largest crop LOX family with remarkable functional diversification maintained under strong selective pressure (92% functional retention). Key stress-responsive genes, particularly
