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

Although neck and low-back pain are common sources of neuropathic pain with high societal costs, the pathophysiology of neuropathic pain is not well-defined. Traditionally, most rodent pain studies rely on evoked reflex-based testing to measure pain. However, these testing methods do not reveal spontaneous pain, particularly early after injury. The rat grimace scale (RGS) for quantifying spontaneous pain has been validated after visceral, incisional, orthopedic, and inflammatory insults but not neuropathic pain. The current study used a rat model of radiculopathy to investigate the time course of RGS, the effect of the NSAID meloxicam on RGS, and the reliability and consistency of RGS across testers. RGS values at baseline and at 3, 6, 24, and 48 h after cervical nerve root compression (NRC) that induced robust evoked pain responses were compared with those obtained after sham surgery. The RGS was also evaluated at 6 h after NRC in another set of rats that had received meloxicam treatment prior to surgery. At 6 h, NRC induced higher RGS scores (1.27 ± 0.18) than did sham surgery (0.93 ± 0.20), and scores remained above baseline for as long as 48 h. Treatment with meloxicam before NRC reduced RGS at 6 h to sham levels, which were lower than those of injury without treatment. The RGS was associated with very good interobserver reliability (intraclass correlation coefficient, 0.91) and excellent internal consistency (Cronbach α, 0.87). These findings suggest that RGS is a useful approach to identifying and monitoring acute neuropathic pain in rats.
