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

Poly(l-lactide) (PLLA) microfibrous scaffolds produced by electrospinning were treated with mild Ar or Ar-NH3/H2 plasmas to enhance cell attachment, growth, and infiltration. Goniometry, atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS) measurements were used to evaluate the modification of the scaffold surface chemistry by plasma treatment. AFM and XPS measurements showed that both plasma treatments increased the hydrophilicity without affecting the integrity of the fibrous structure and the fiber roughness, whereas Ar-NH3/H2 plasma treatment also resulted in surface functionalization with amine groups. Culture studies of bovine aorta endothelial cells and bovine smooth muscle cells on the plasma-treated PLLA scaffolds revealed that both Ar and Ar-NH3/H2 plasma treatments promoted cell spreading during the initial stage of cell attachment and, more importantly, increased the cell growth rate, especially for Ar plasma treatment. In vitro cell infiltration studies showed that both plasma treatments effectively enhanced cell migration into the microfibrous scaffolds. In vivo experiments involving the subcutaneous implantation of plasma-treated PLLA scaffolds under the skin of Sprague-Dawley rats also showed increased cell infiltration. The results of this study indicate that surface treatment of PLLA microfibrous scaffolds with mild Ar or Ar-NH3/H2 plasmas may have important implications in tissue engineering. Further modifications with bioactive factors should improve the functions of the scaffolds for specific applications.
