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

Protease-activated receptor 2 (PAR(2)) is involved in airway inflammation and airway hyperresponsiveness; both are the prominent features of asthma. Transient receptor potential vanilloid receptor 1 (TRPV1) is expressed in pulmonary sensory nerves, functions as a thermal and chemical transducer and contributes to neurogenic inflammation. Using cell-attached single-channel recordings we investigated the effect of PAR(2) activation on single TRPV1channel activities in isolated pulmonary sensory neurons. Our immunohistochemical study demonstrated the expression of PAR(2) in rat vagal pulmonary sensory neurons. Our patch clamp study further showed that intracellular application of capsaicin (0.75 microM) induced single channel current that exhibited outward rectification in these neurons. The probability of the channel being open (Po) was significantly increased after the cells were pretreated with PAR2-activating peptide (100 microM, 2 min). Pretreatment with trypsin (0.1 microM, 2 min) also increased the single-channel Po, and the effect was completely inhibited by soybean trypsin inhibitor (0.5 microM, 3 min). In addition, the effect of PAR2 activation was abolished by either U73122 (1 microM, 4 min),a phospholipase C inhibitor, or chelerythrine (10 microM, 4 min), a protein kinase C inhibitor. In conclusion, our data demonstrated that activation of PAR2 upregulated single-channel activitiesofTRPV1and that the effect was mediated through the protein kinase C-dependent transduction pathway.
