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

Constrictive bronchiolitis obliterans (CBO), a highly fatal syndrome seen following toxicant exposure and lung transplantation, is in need of mechanistic study. This report creates an animal model of toxicant induced CBO, validates its pathology and suggests a physiologic mechanism for its origin. Papaverine, the alkaloid in Sauropus plants and responsible for human toxicant-induced CBO, was used to create the rat model. A mini-osmotic pump delivered papaverine intratracheally for up to 28 days (0.25 microL/hr, totaling 6.4 mg). Bronchoalveolar lavage (BAL) was measured. Lung tissue was evaluated for signs of CBO (H&E and Trichrome staining). Cytokines deregulated in human CBO were also measured (TGF-beta and eNOS). Peribronchial inflammation, extensive denudation and destruction of bronchial mucosa, as well as increased peribronchial collagen (all classic signs of CBO) were observed as early as 7 days in papaverine treated animals, with more extensive damage after 28 days. Significant elevations of TGF-beta and eNOS were seen in lung homogenates. Our toxicant induced model of CBO via a novel delivery method of intratracheal papaverine accurately reproduces pathology and cytokine profiles of human CBO. Papaverine has potential for producing CBO by multiple routes. This model introduces a vehicle for both understanding and development of innovative treatment for CBO.
