Comparison of the airway hyperreactivity produced by single and multiple antigen exposures in sensitized guinea pigs.
Article in Agents and actions, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Chronic airway hyperreactivity is a hallmark feature of asthma, but animal models of airway hyperreactivity often utilize a single antigen challenge. Therefore, we compared the airway hyperreactivity produced by single and multiple antigen challenges in ovalbumin-sensitized guinea pigs. Significant (2-fold) leftward shifts in dose-response curves for i.v. methacholine- or LTD4-induced bronchoconstriction in anesthetized and ventilated animals occurred 24 h following a single ovalbumin challenge. This nonspecific airway hyperreactivity was prevented by pretreatment with ketotifen or dexamethasone. However, airway hyperreactivity was no greater 24 h following the last of 3 daily antigen challenges than after 1 challenge and was absent 72 h following one antigen challenge. These results raise concern over the similarity of antigen-induced airway hyperreactivity in guinea pigs to the chronic airway hyperreactivity in asthmatics.
