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

Neurobehavioral and neurophysiological actions of the peptide endothelin-1 (ET-1) were investigated after subcutaneous plantar hindpaw injections in adult male Sprague Dawley rats. Hindpaw flinching developed within minutes after ET-1 (8-16 nmol) injection, peaked at 30 min, lasted for 60 min, and was strongly inhibited by the endothelin-A (ET(A)) receptor antagonist, BQ-123 (3.2 m). In separate experiments, impulse activity of single, physiologically characterized sensory C-, Adelta-, and Abeta-fibers was recorded from the sciatic nerve in anesthetized rats after subcutaneous injections of endothelin-1 (1-20 nmol), alone or together with BQ-123 (3.2 m), into the plantar hindpaw receptive fields of these units. All nociceptive C-fibers (31 of 33 C-fibers studied) were excited by ET-1 (1-20 nmol) in a dose-dependent manner. For doses of 16-20 nmol, the mean latency for afferent activation after injection of ET-1 was 3.16 +/- 0.31 min, and the mean and maximum response frequency were 2.02 +/- 0.48 impulses (imp)/sec and 14.0 +/- 3.2 imp/sec, respectively. All 10 nociceptive Adelta-fibers (of 12 Adelta-fibers studied) also responded to 1-20 nmol of ET-1 in a dose-dependent manner with a mean latency of 3.5 +/- 0.12 min and mean response frequency of 3.3 +/- 2.3 imp/sec. In contrast, most Abeta-fibers (9 of 12) did not respond to ET-1. BQ-123, when coinjected with ET-1, blocked ET-1-induced activation in all C- and Adelta-fibers tested. These data demonstrate that subcutaneous administration of ET-1 to the rat plantar hindpaw produces pain-like behavior and selective excitation of nociceptive fibers through activation of ET(A) receptors.
