Calcitonin gene-related peptide potentiates substance P-induced plasma extravasation in the rat trachea.
Article in Lung, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Antidromic stimulation of vagal sensory nerves is known to produce plasma extravasation in the rat trachea. This neurogenic inflammation is thought to be mediated by substance P or other tachykinins released from sensory nerve endings. We sought to determine whether calcitonin gene-related peptide (CGRP), which is also released from sensory nerve endings, can potentiate substance P-induced plasma extravasation in the rat trachea. To accomplish this, we measured the amounts of Evans blue dye extravasated into the trachea after intravenous injections of substance P alone and combined with CGRP. We found that when substance P and CGRP were injected together, the amount of plasma extravasation produced in the trachea was substantially greater than the amount produced when substance P was injected alone. This potentiation was critically dependent on the dosage of CGRP and was not observed when relatively high dosages were used. We also found that CGRP had a potent hypotensive effect and speculate that reduced blood pressure may account for the lack of potentiation observed at the higher CGRP dosages. Based on these findings, we conclude that CGRP can potentiate substance P-induced plasma extravasation in the rat trachea and may therefore play a role in modulating neurogenic inflammation of the airways.
