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
MAIN
conclusionThis study uncovered potential regulatory networks associated with cleistogamy in pigeonpea by analyzing interactions between lncRNAs, mRNAs, and miRNAs. Cleistogamy, a unique floral adaptation, is a valuable trait offering a unique reproductive advantage in self-pollinated species. In crops like pigeonpea, outcrossing significantly contributes to the deterioration of varietal purity, impacting the overall seed purity. Thus, as a primary effort to get molecular insights governing cleistogamy in pigeonpea, we performed RNA-seq analysis of unopened flower buds from three pigeonpea genotypes having different flower morphologies i.e., ICPL87154 (cleistogamous), ICPL87119 (chasmogamous), and UP26 (partially wrapped petals). Comparative analysis revealed differential gene expression patterns in the cleistogamous vs. chasmogamous combination. Comparative transcriptome profiling identified differential enrichment of biological pathways between the genotypes. Relative to the non-cleistogamous genotype, the cleistogamous genotype exhibited increased expression of genes involved in carbohydrate metabolism and ubiquitin-mediated proteolysis, whereas genes associated with hormone signaling and endocytosis showed reduced expression. To further delineate the regulation, LncRNAs were predicted from the assembled transcriptome, and a total of 25,307 transcripts were identified as lncRNAs based on length, exon number, and coding potential. Further interaction analysis revealed regulatory lncRNA-miRNA-mRNA networks, and expression validation of key networks uncovered some candidate genes, such as FT-interacting protein 1 (FTIP1) and auxin response factor 2A, that can be potentially involved in this trait. Upregulation of miRNAs miR156b, miR169g, and miR171g in the cleistogamous genotype suggests the post-transcriptional regulation of cleistogamy. Additionally, simple sequence repeats (SSRs) identified in differentially expressed genes and lncRNAs offer additional genomic resources pertaining to this trait. This study provides the first comprehensive identification of DEGs and DE-lncRNAs associated with cleistogamy in pigeonpea, laying the groundwork for further molecular dissection.
