Prevalence and treatment of facet syndrome in patients with lumbar spinal stenosis managed with posterior lumbar vertebral spinal stabilization FFX
Article in Journal of craniovertebral junction & spine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Facet joint degeneration represents a common source of low back pain and contributes to the development of lumbar spinal stenosis (LSS). We sought to identify the prevalence of facet syndrome in patients with LSS planned to undergo decompression and placement of facet cages (FFX Materials and Methods: LSS patients undergoing decompression and placement of facet cages performed for a period of 1 year were included. Patients who did not undergo an MBB test prior to surgery were excluded. Results: A total of 22 patients met the inclusion criteria for the study. The mean age was 69.4 ± 12.9 years with a majority of patients (63.6%) being female. Sixteen of the 22 (73%) patients had a positive MBB test. VAS scores were similar at baseline between the MBB positive and negative subgroups. The improvement in postoperative VAS back scores compared to baseline was greater for patients with a positive block test compared to those with a negative test (-4.7 vs. -1.8, respectively). As expected with the decompression part of the procedure, the improvement of VAS leg scores was similar for patients with positive and negative block tests compared to baseline. Conclusion: The present study documents the high prevalence of facet syndrome in patients with LSS and the clinical benefits associated with the use of facet fusion cages to reduce facet-generated back pain.
