1 · What the graph read from it

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.

2 · The registry

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

Scleroderma is a chronic disorder manifested by excessive synthesis and deposition of collagen in skin and connective tissue, vascular abnormalities, and autoimmunity. Using microarray and real-time PCR data, we show that intradermally expressed interferon γ (IFN-γ), generated after intradermal injection of IFN-γ-coding plasmid, and non-invasive topical nanoparticle (TNP) treatment with IFN-γ-coding plasmid, decreased collagen synthesis (via the Jak/Stat 1 pathway), upregulated Th1 cytokine levels, and downregulated the profibrotic cytokine Transforming growth factor β and the Smad pathways in the Tsk/+ (tight-skin scleroderma) mouse model. The TNP gene delivery system was constructed from gemini surfactant 16-3-16 and IFN-γ-coding plasmid. Topical administration of IFN-γ-coding plasmid in TNPs was effective in expressing IFN-γ levels after a 20-day treatment regimen without increased TLR4, CCL2, CCL11 and CCR2 mRNA levels that were observed in injected animals, signs considered to be innate responses to injury. The more uniform transgene IFN-γ expression caused significant (70-72%) collagen reduction, as assessed by reverse transcription real-time PCR. These results demonstrate efficient in vivo transfection using a gemini surfactant-based TNP delivery system able to modulate excessive collagen synthesis in scleroderma-affected skin.
