1 · What the graph read from it

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.

2 · The registry

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

Calcitonin gene-related peptide (CGRP)-, tachykinins- and somatostatin-immunoreactive neurones in rat dorsal root ganglia have been studied by means of single and double immunogold labelling techniques. Peptide-immunoreactive neurones are generally B- or C-type cells of small size, with well developed rough endoplasmic reticulum and scanty neurofilaments. In neurones classifiable as A2-type cells, i.e. larger neurones with a lighter cytoplasm due to the presence of poorly developed Nissl bodies and numerous neurofilaments, only CGRP immunoreactivity was detected. Immunolabelled structures were identified as large (60-100 nm diameter), electron-dense, membrane-bounded p-type granules. They were observed only in neuronal cell bodies or in the intraganglionic portions of the axons. No granules immunoreactive to the antisera applied in this study were observed in non-neuronal cells. Immuno-staining experiments with different combinations of the antisera revealed, in some cells, the presence of double immunolabelled granules; in particular localization of CGRP and tachykinins, CGRP and somatostatin, and tachykinins and somatostatin to single secretory granules was demonstrated. The finding that more than one peptide is localized to the same secretory granule supports the postulate that peptides are co-released upon nerve stimulation providing morphological support for physiological and pharmacological data demonstrating an interaction between different peptides in the modulation of synaptic activity.
