Calcitonin gene-related peptide and its mRNA in pulmonary neuroendocrine cells and ganglia.
Article in Histochemistry, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The occurrence of calcitonin gene-related peptide (CGRP) and it's mRNA was studied in lungs of rats and piglets using in situ hybridization with two synthetic oligonucleotide probes followed by immunocytochemistry (ICC). CGRP mRNA was present in pulmonary neuroendocrine cells (PNEC) of both the solitary type and cluster type (neuroepithelial body; NEB) at all levels of the airway epithelium from bronchi to alveoli. The distribution of labelled cells was similar to that previously described with ICC. The 44-mer probe provided stronger hybridization signal than the 34-mer and the two combined increased labelling slightly. Formalin fixation reduced labelling and tended to increase background. Labelling for CGRP mRNA was evenly distributed over the cytoplasm, whereas CGRP-like immunoreactivity (LI) usually was of highest intensity toward the base of the PNEC, suggesting basal accumulation of synthesized peptide. CGRP-LI was also observed in occasional rat ganglia and in some, but not all, piglet ganglia. These local neurons may contribute to the CGRP fibers of airways and vasculature, and could theoretically bridge their dendrites and axons between NEB and the effector organ (e.g. artery or arteriole) thus accomplishing a function similar to the postulated axon reflex.
