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
PIWI-interacting RNA (piRNA) is a class of recently discovered small non-coding RNAs. piRNAs derive from an initial transcript encompassing a piRNA cluster via a unique biosynthesis process, interact with PIWI proteins, bind to specific targets, and recruit chromatin modifiers to enable transcriptional repression. Abnormal expression of PIWI proteins and piRNAs has been reported in some human cancers, with participation of some PIWI/piRNAs complexes in tumorigenesis and association with cancer prognosis. Their expression in patients with systemic sclerosis (SSc) has not been widely elucidated. PIWI/piRNAs and their role in the pathogenesis of collagen accumulation in SSc was therefore investigated; no difference was found in the PIWIL1-4 levels between normal and cultured SSc dermal fibroblasts. Among piRNAs predicted to target SSc-related molecules, we first found significant piR-32364 up-regulation in SSc dermal fibroblasts, likely due to intrinsic TGF-β signaling. Forced piR-32364 overexpression in normal fibroblasts significantly reduced COL1A1 expression both at mRNA and protein levels, but not COL1A2. Thus, piR-32364 overexpression in SSc fibroblasts may be the negative feedback against collagen up-regulation, which could suggest the potential of piRNAs as a therapeutic target.
