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
The biological basis of the high clinical heterogeneity of T-LGL Leukemia (T-LGLL) is not completely understood and effective therapies for this disease are lacking. Through RNA-Sequencing of purified T-LGLs we reveal gene expression profiles and pathway dysregulations in the major patient subgroups, defined by CD8+ or CD4+ phenotype and STAT3/STAT5B mutational status. Overall, T-LGLL patients exhibited a marked transcriptome dysregulation compared to controls. This was more pronounced in the most symptomatic CD8 + STAT3-mutated patients, which emerged as a distinct biological entity, separated from the other disease subgroups. Particularly, CD8 + STAT3-mutated cases displayed extensive down-regulation of genes, ultimately resulting in the de-repression of proliferation and cell cycle pathways. Among genes up-regulated in CD8 + STAT3-mutated cases we found VCAM1, the transcriptional repressor EZH2 and the p53-regulator MDM2 proto-oncogene, as well as the leukemogenesis-associated PVT1 up-regulation, representing the first report of a long-non-coding RNA alterations in leukemic T-LGLs. The impact of STAT5B mutations on T-LGLs transcriptome was more limited and the overexpression of the PIM1 serine/threonine kinase proto-oncogene was identified as one of the most relevant features of STAT5B-mutated CD4 + T-LGLL. This study significantly advances our understanding of T-LGLL pathogenesis, uncovering new oncogenic mechanisms within the distinct molecular subtypes of the disease.
