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

The effect of diabetes mellitus on opiate-mediated inhibition of calcium current density (I(D Ca) [pA pF-1]) and cytosolic calcium response ([Ca2+]i nM) to depolarization with elevated KCl and capsaicin was assessed. Experiments were performed on isolated, acutely dissociated dorsal root ganglion (DRG) neurons from diabetic, BioBreeding/Worcester (BB/W) rats and age-matched control animals. Sciatic nerve conduction velocity was significantly decreased in diabetic animals compared to controls. Mean I(DCa) and [Ca2+]i responses to capsaicin and elevated KCl recorded in DRGs from diabetic animals were significantly larger than those recorded in DRG neurons from controls. In neurons from diabetic animals, the opiate agonist dynorphin A (Dyn A; 1, 3, and 5 microM) had significantly less inhibitory effect on I(D Ca) and KCl-induced [Ca2+]i responses compared to controls. Omega-conotoxin GVIA (omega-CgTX; 10 microM) and pertussis toxin (PTX; 250 ng ml-1) abolished Dyn A-mediated inhibition of I(DCa) and [Ca2+]i in control and diabetic neurons, suggesting that Dyn A modulated predominantly N-type calcium channels coupled to opiate receptors via PTX-sensitive (Gi/o) inhibitory G proteins. These results suggest that opiate-mediated regulation of PTX-sensitive, G protein-coupled calcium channels is diminished in diabetes and that this correlates with impaired regulation of cytosolic calcium.
