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

1 Platelet activating factor (PAF), but not the carrier molecule bovine serum albumin (BSA) induced bronchoconstriction in the anaesthetized rabbit. This bronchoconstriction was not altered by prior treatment with capsaicin. 2 Rabbits demonstrated increased airways responsiveness to histamine 24h after exposure to PAF but not to BSA. PAF failed to increase airways responsiveness to histamine in animals pretreated with capsaicin (80 mg kg-1). 3 A significant increase in inflammatory cells was obtained in bronchoalveolar lavage (BAL) 24h after PAF exposure in vehicle-treated rabitts. This was associated with an increase in the numbers of neutrophils and eosinophils. Capsaicin treatment inhibited the PAF-induced influx of inflammatory cells found in BAL, although this was not associated with an inhibition of PAF-induced pulmonary eosinophilia. 4 Capsaicin-induced motor effects were modest in epithelium-intact rabbit bronchial preparations, but were significantly enhanced in epithelium-denuded preparations in the presence of thiorphan. The contractile response to capsaicin was significantly inhibited in tissues exposed to a consecutive dose of capsaicin. Furthermore, ruthenium red abolished capsaicin-induced contraction in epithelium-denuded preparations. 5 Tissue content of calcitonin gene-related peptide-like immunoreactivity and substance P-like immunoreactivity was not reduced in bronchus and iris obtained from capsaicin-treated rabbits, although capsaicin-induced contractile responses in rabbit bronchus obtained from animals previously treated with capsaicin were significantly reduced. Furthermore, airway responses to histamine, methacholine and electrical field stimulation in vitro, were not altered by pretreatment of rabbits in vivo for 3 days with capsaicin. 6. In conclusion, PAF-induced airways responsiveness and pulmonary cell accumulation is inhibited by in vivo capsaicin pretreatment in the rabbit, via a mechanism that may not involve depletion of sensory neuropeptides.
