Single-cell transcriptomic data reveal the increase in extracellular matrix organization and antigen presentation abilities of fibroblasts and smooth muscle cells in patients with pelvic organ prolapse.
Article in International urogynecology journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introduction and hypothesisWe aimed to explore the cellular properties of fibroblasts and smooth muscle cells (SMCs), the two major cell types of the vagina wall, in pelvic organ prolapse (POP) to improve the knowledge of the underlying molecular mechanisms of POP.
methodsThe single-cell RNA sequencing (scRNA-seq) profile GSE151202 was downloaded from NCBI Gene Expression Omnibus, in which vaginal wall tissues were harvested from patients with anterior vaginal wall prolapse and control subjects respectively. The scRNA-seq data of samples (5 POP and 5 controls) were adopted for analysis. Cluster analysis was performed to identify the cell subclusters. Trajectory analysis was applied to construct the differentiation trajectories of fibroblasts and SMCs. Cellular communication analysis was carried out to explore the ligand-receptor interactions between fibroblasts/SMCs and immune cells.
resultsTen subclusters were determined in both groups, among which fibroblasts and SMCs were the most abundant cell types. Compared with controls, fibroblasts increased whereas SMCs declined in POP. During the transition of fibroblasts and SMCs from a normal into a disease state, extracellular matrix organization and antigen presentation were heightened. The intercellular communications were altered in POP. Interactions between fibroblasts/SMCs and macrophages/natural killer/T cells were strengthened as more ligand-receptor pairs involved in antigen presentation pathways were gained in POP.
conclusionExtracellular matrix organization and antigen presentation abilities of fibroblasts and SMCs were enhanced in POP.
