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

It has become apparent that the numerous growth factors and cytokines are produced during the development of fibroproliferative lung disease. Investigators must sort out which combinations of these factors are playing mechanistic roles in the disease process. Here we demonstrate that transforming growth factor (TGF)-alpha, a potent epithelial and mesenchymal cell mitogen, is upregulated specifically at the sites of asbestos fiber deposition in the lungs of rats exposed for 5 hours. Unexposed animals and those exposed to high concentrations of iron spheres exhibited no increase in TGF-alpha expression at any time during the experiment. Inhaled asbestos fibers deposit initially at the bronchiolar-alveolar duct regions and alveolar macrophages accumulate at these sites within hours. Non-isotopic in situ hybridization and immunohistochemistry were used to show that the mRNA that codes for TGF-alpha along with the peptide were clearly up-regulated at the bronchiolar-alveolar duct regions by 24 hours after the single asbestos exposure. The numbers of labeled cells demonstrated that expression of the mRNA and protein remained significantly above background for at least 2 weeks after exposure along with increased cell proliferation assessed by staining for proliferating cell nuclear antigen. This, to our knowledge, is the first demonstration of TGF-alpha expression at sites of lung injury in developing fibroproliferative disease. This finding supports the hypothesis that the growth factor is involved in the dramatic epithelial and mesenchymal proliferation we documented previously, although additional experiments will be essential to establish the precise role of TGF-alpha.
