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.
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. Acute exposure to ozone is known to cause airway hyperresponsiveness, which, at least in part, seems to result from an increase in the permeability of the airway mucosa. Recently, we demonstrated that depletion of sensory neuropeptides inhibits the ozone-induced increase in the permeability of the tracheal mucosa in guinea-pigs. The aim of this study was to determine whether tachykinins mediate ozone-induced increase in the permeability of the tracheal mucosa in guinea-pigs. 2. Anaesthetized guinea-pigs were exposed to either 3 p.p.m. ozone or filtered air for 30 min. Immediately after exposure, a tracheal segment was isolated in vivo and administered with horseradish peroxidase (HRP). The permeability was assessed by monitoring the appearance of HRP in the blood. 3. A low dose of NKA increased the permeability of the tracheal mucosa, whereas a low dose of SP was without effect. Low and high doses of the selective NK(3) receptor agonist, senktide, were also without effect. The effect of a low dose of NKA was abolished by the NK(2) receptor antagonist, SR-48,968. A high dose of SP increased the permeability in a manner reversible by the NK(1) receptor antagonist, CP-96,345. 4. Pretreatment with SR-48,968 completely inhibited the ozone-induced increase in the permeability, whereas CP-96,345 had no effect. 5. It is thus concluded that endogenous tachykinins mediate the ozone-induced increase in the permeability of the tracheal mucosa in guinea-pigs mainly via NK(2) receptor activation.
