Electrophysiological properties of the airway: epithelium in the murine, ovalbumin model of allergic airway disease.
Article in The American journal of pathology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The electrophysiological properties of cultured tracheal cells (CTCs) were examined in a murine (C57BL/6J), ovalbumin (OVA)-induced model of allergic airway disease (AAD) at early (3-day OVA-aerosol) and peak (10-day OVA-aerosol) periods of inflammation. Transepithelial potential difference, short-circuit current (Isc), and resistance (RT) were lower in CTCs from 10-day OVA-aerosol animals compared to CTCs from naïve mice. In cells cultured for 5 weeks, RT was greater in naive CTCs than in 10-day OVA-aerosol CTCs at all times (P < 0.01). The Isc response to mucosal amiloride (10(-4) mol/L) was increased in CTCs from 10-day OVA-aerosol mice compared to naïve mice (6.0 +/- 0.37 microA/cm2 versus 1.8 +/- 0.56 microA/cm2; P < 0.001) with intermediate values for CTCs from 3-day OVA-aerosol mice. The cAMP-induced increase in Isc was blunted in 10-day OVA-aerosol animals compared to CTCs from naïve mice (9 +/- 12% versus 39 +/- 7%; P < 0.01) with intermediate values for CTCs from 3-day OVA-aerosol mice. There was no difference in mannitol flux in naïve compared to 10-day OVA-aerosol CTCs. Similar results were found using intact tracheas mounted in a perfusion chamber. These data demonstrate changes in airway epithelial cell function in the OVA-induced model of AAD that may contribute to the pathogenesis of airway inflammation.
