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
Increased resistance of airways or blood vessels within the lung is associated with asthma or pulmonary hypertension and results from contraction of smooth muscle cells (SMCs). To study the mechanisms regulating these contractions, we developed a mouse lung slice preparation containing bronchioles and arterioles and used phase-contrast and confocal microscopy to correlate the contractile responses with changes in [Ca(2+)](i) of the SMCs. The airways are the focus of this study. The agonists, 5-hydroxytrypamine (5-HT) and acetylcholine (ACH) induced a concentration-dependent contraction of the airways. High concentrations of KCl induced twitching of the airway SMCs but had little effect on airway size. 5-HT and ACH induced asynchronous oscillations in [Ca(2+)](i) that propagated as Ca(2+) waves within the airway SMCs. The frequency of the Ca(2+) oscillations was dependent on the agonist concentration and correlated with the extent of sustained airway contraction. In the absence of extracellular Ca(2+) or in the presence of Ni(2+), the frequency of the Ca(2+) oscillations declined and the airway relaxed. By contrast, KCl induced low frequency Ca(2+) oscillations that were associated with SMC twitching. Each KCl-induced Ca(2+) oscillation consisted of a large Ca(2+) wave that was preceded by multiple localized Ca(2+) transients. KCl-induced responses were resistant to neurotransmitter blockers but were abolished by Ni(2+) or nifedipine and the absence of extracellular Ca(2+). Caffeine abolished the contractile effects of 5-HT, ACH, and KCl. These results indicate that (a) 5-HT and ACH induce airway SMC contraction by initiating Ca(2+) oscillations, (b) KCl induces Ca(2+) transients and twitching by overloading and releasing Ca(2+) from intracellular stores, (c) a sustained, Ni(2+)-sensitive, influx of Ca(2+) mediates the refilling of stores to maintain Ca(2+) oscillations and, in turn, SMC contraction, and (d) the magnitude of sustained airway SMC contraction is regulated by the frequency of Ca(2+) oscillations.
