Pharmacological characterisation of neurokinin receptors mediating anion secretion in rat descending colon mucosa.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Substance P (SP), neurokinin A (NKA), neurokinin B (NKB), [Sar9, Met (O2)11]-SP (SMSP), senktide, [beta Ala8]-NKA(4-10) and neuropeptide gamma (NP gamma) all stimulate secretory responses in rat descending colon mucosa under voltage clamp conditions. Secretory responses (measured as short circuit current under voltage clamp conditions) were transient and those evoked by SP, SMSP, NKA and senktide were significantly reduced by pretreating tissues with the chloride channel blocker, diphenylamine carboxylate (DPC). Concentration-response curves showed varying degrees of sensitivity to tetrodotoxin (TTX). Senktide-induced secretion was virtually abolished by TTX, while NP gamma and [beta Ala8]-NKA(4-10) were not significantly altered. Rightward shifts of concentration-response curves were observed for SMSP, NKA and SP in TTX treated preparations compared with controls. NKA response curves in the presence of TTX were further inhibited by MEN10,207 and CP-96,345. GR71251, GR82334 and CP-96,345 all inhibited SMSP secretory responses with pA2 values of 5.8, 6.5 and 6.9 respectively. In conclusion three types of neurokinin receptor exist in preparations of rat colon mucosa and their relative location within neuronal and epithelial surfaces are discussed.
