Autocrine SFRP2 (secreted frizzled related protein 2) enhances lung myofibroblast fibrogenic activity by suppressing PINK1-mediated mitophagy initiation.

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
Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease driven by persistent activation of pulmonary myofibroblasts, but the regulatory mechanisms sustaining this pathological state remain incompletely understood. Using single-cell RNA sequencing (scRNA-seq), we identified SFRP2 (secreted frizzled related protein 2) as a critical mediator of profibrotic myofibroblasts in IPF lungs. Functional studies revealed that SFRP2 acted in an autocrine manner to promote myofibroblast activation and extracellular matrix (ECM) production. Mechanistically, SFRP2 activated FZD5-mediated non-canonical WNT-Ca
