Symmetry of paraspinal muscle denervation in clinical lumbar spinal stenosis: support for a hypothesis of posterior primary ramus stretching?
Trial report in Muscle & nerve, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
introductionDenervation of the paraspinal muscles in spinal disorders is frequently attributed to radiculopathy. Therefore, patients with lumbar spinal stenosis causing asymmetrical symptoms should have asymmetrical paraspinal denervation.
methodsSeventy-three patients with clinical lumbar spinal stenosis, aged 55-85 years, completed a pain drawing and underwent masked electrodiagnostic testing, including bilateral paraspinal mapping and testing of 6 muscles on the most symptomatic (or randomly chosen) limb.
resultsWith the exception of 10 subjects with unilateral thigh pain (P = 0.043), there was no relationship between side of pain and paraspinal mapping score for any subgroups (symmetrical pain, pain into 1 calf only). Among those with positive limb EMG (tested on 1 side), no relationship between side of pain and paraspinal EMG score was found.
conclusionEvidence suggests that paraspinal denervation in spinal stenosis may not be due to radiculopathy, but rather due to stretch or damage to the posterior primary ramus.
