Calcitonin gene-related peptide, enkephalin and serotonin coexist in neuroepithelial bodies of the respiratory tract of the red-eared turtle, Pseudemys scripta elegans. An immunocytochemical study.
Article in Histochemistry, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 lungs of the red-eared turtle, Pseudemys scripta elegans, have been investigated by light-microscopical immunocytochemistry for serotonin (5-HT) and the neuropeptides calcitonin gene-related peptide (CGRP), enkephalin (ENK), bombesin, somatostatin, calcitonin and cholecystokinin. CGRP- or 5-HT-like immunoreactivity (LI) was demonstrated in neuroepithelial bodies (NEBs) and solitary neuroepithelial endocrine cells lying between the ciliated epithelial cells of the intrapulmonary bronchi, and of the primary, secondary and tertiary trabeculae. Furthermore, ENK-LI NEBs were found between the trabecular ciliated epithelial cells. No reaction was observed with antisera against bombesin, somatostatin, calcitonin, and cholecystokinin. Using consecutive sections, CGRP-LI appears to be colocalized with 5-HT-LI in NEB cells. In addition, it was demonstrated that all the ENK-LI NEBs also contain CGRP-LI, whereas only a part of the CGRP-LI NEBs reveal ENK-LI. To our knowledge this is the first demonstration of CGRP- and/or ENK-LI in pulmonary NEBs of a lower vertebrate.
