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 Src tyrosine kinase family contributes to the signalling mechanism mediating serotonin (5-hydroxytryptamine (5-HT))-induced vasoconstriction. These kinases were reported to influence the calcium sensitivity of the contractile apparatus. Whether Src kinases affect also the intracellular calcium concentration during constriction of intact arteries is unknown. Thus, we tested the hypothesis that constriction of arteries is associated with a Src kinase-dependent alteration of the intracellular calcium concentration. Contractility of gracilis arteries of Wistar rats was studied using isometric and isobaric myography. The intracellular calcium concentration was measured simultaneously with tension by FURA-2 fluorimetry. Inhibition of Src kinases with 10 μM PP2, 30 μM dasatinib and 100 μM AZM 475271 resulted in a strong attenuation of 5-HT-induced contractions. Vessel incubation with 10 μM PP3, an inactive analogue of PP2, had no effect. Removal of the endothelium did not alter vessel contractile responses to 5-HT nor the action of the Src-kinase inhibitor PP2. The PP2-mediated inhibition of 5-HT-induced contraction was associated with a reduced response of [Ca
