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. Using a guinea-pig model of allergic asthma, we investigated the role of L-arginine limitation in the allergen-induced deficiency of nitric oxide (NO) and airway hyperreactivity (AHR) after the early asthmatic reaction, by examining the effects of various concentrations of the NO synthase (NOS) substrate on the responsiveness to methacholine of isolated perfused tracheae from unchallenged (control) animals and from animals 6 h after ovalbumin challenge. 2. Preparations from ovalbumin-challenged guinea-pigs showed a 1.9 fold increase in the maximal response (Emax) to intraluminal (IL) administration of methacholine compared to controls (P<0.001). A similar 2.0 fold (P<0.05) increase in Emax to methacholine was observed in control airways incubated with the NOS inhibitor Nomega-nitro-L-arginine methyl ester (L-NAME; 0.1 mM, IL), while L-NAME had no further effect on the airways from ovalbumin-challenged animals. 3. In control airways, extraluminal (EL) administration of 0.3, 1.0 and 5.0 mM L-arginine all suppressed the Emax for methacholine by approximately 40% (P<0.01 all), whereas 5.0 mM D-arginine (EL) had no effect. 4. L-Arginine dose-dependently reduced the AHR to methacholine in tracheae from ovalbumin-challenged guinea-pigs, the responsiveness being normalized in the presence of 5.0 mM L-arginine. As in controls, 5.0 mM D-arginine was without effect. 5. The results demonstrate that deficiency of endogenous NO contributes to the allergen-induced AHR to methacholine after the early asthmatic reaction, which is reversed by exogenous administration of L-arginine. This indicates that limitation of substrate may underly the reduced cNOS activity and subsequent AHR after the acute asthmatic response.
