Single-Cell RNA Sequencing of Peripheral Blood Mononuclear Cells in Patients With Single Ventricle/Hypoplastic Left Heart Syndrome.
Article in The journal of gene medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSingle ventricle and hypoplastic left heart syndrome (SV/HLHS) has detrimental effects on multiple organ systems, including peripheral blood mononuclear cells (PBMCs), and can weaken the immune system, exacerbating the risk of infection and various cardiovascular complications.
methodsUsing single-cell RNA sequencing (scRNA-seq), we studied PBMCs from 33 pediatric patients (10 females and 23 males) with SV/HLHS. By a pair-wide study design, the SV/HLHS patients were compared to 33 controls without heart disease.
resultsFour cell types account for the top 62% cumulative importance of disease effects on gene expression in different cell types, that is, Th1/17 cells, TFH cells, NK cells, and Th2 cells. Significant sex differences were observed in TFH Cells, with less prominent effects in females. A total of 6659 genes in different cell types were significantly differentially expressed (DE). Hierarchical clustering by WGCNA analysis of the DE genes revealed that DE genes in NK cells are most closely related to those in SV/HLHS. A total of 822 genes showed cell-specific DE with opposite directions in different cell types, highlighting overrepresented MYC and IFN-γ activity in T cell and NK cell populations, as well as underrepresentation in monocytes and Treg cells.
conclusionThis study elucidates the complex transcriptome landscape in PBMCs in patients with SV/HLHS, emphasizing the differential impacts on various cell types. New insights are gained into the precise modulation of MYC and IFN-γ activity in SV/HLHS, which may help balance immune responses and reduce harmful inflammation, and promote effective tissue repair and infection control.
