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

Background: Pulsed radiofrequency (PRF) has been used for the treatment of chronic lumbar radicular pain and other chronic pain states. The dorsal root ganglion (DRG) consists of primary afferent somatic and visceral nerve cell bodies that transduce sensory signals from the periphery to the central part of the nervous system. It is a very important part of acute nociception, as well as the development and maintenance of chronic pain. Methods: A total of seven domestic pigs were investigated. All pigs underwent a PRF procedure while under general anesthesia and with X-ray imaging. Four lumbar DRGs were randomly treated. We used the opposite side of the DRGs as controls. The lumbar region of the spine was placed in 10% formaldehyde for one month. After this fixation, DRG samples were prepared for slide analysis. Results: Nestin (Nes, code-Nr. AB 5968, dilution 1:250, rabbit, Abcam, United Kingdom) and matrix metallopeptidase 2 (MMP-2, code-Nr. DUB 03, dilution 1:100, goat) expressions were detected by immunohistochemical staining. The cell numbers with Nes (28.4 ± 3.3 vs. 16.1 ± 3.4; P < 0.05) and MMP-2 (26.2 ± 3.2 vs. 14.1 ± 2.3; P < 0.05) expressions were larger on the PRF side compared to the control side. The glial cells in the spinal ganglia on both sides showed immunoreactivity. Conclusions: The increase of MMP-2-containing gangliocytes one month after PRF procedures highlights active neural cell proliferation. Increased Nes factor expression in spinal gangliocytes of the lumbar region indicates neural remodeling and regeneration.
