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
purposeTo identify common pain distribution patterns on digital pain diagrams (PDs) in patients with lumbar spinal stenosis (LSS) presenting to a secondary spine care setting.
methodsPatients presenting to a secondary spine center with a diagnostic code for LSS and a completed PD were included. Latent class analysis of PDs was used to identify unique pain distribution patterns. The final class solution was selected based on the most suitable combination of the Bayesian Information Criterion, posterior probabilities, minimum class size, and the clinical interpretability of the LSS pain pattern distributions.
resultsA total of 2,379 patients with LSS were included. A six-class model of LSS pain distribution patterns was the preferred model solution. Class 1 (11.4%) represented a bilateral posterior leg pain (11.4%) distribution pattern; Class 2 (8.7%) bilateral posterior and anterior leg pain; Class 3 (26.1%) unilateral posterior leg pain; Class 4 (21.0%) unilateral posterior leg pain with low back pain; Class 5 (22.9%) unilateral anterior and posterior leg pain; and Class 6 (9.9%) multisite pain.
conclusionWe identified clinically recognizable pain distribution patterns in patients with LSS presenting to a secondary spine center in Denmark. These preliminary pain distribution patterns may represent clinical LSS phenotypes, but at minimum suggest that heterogenous pain presentations are common in people with LSS. Future work is needed to validate these pain distribution patterns in other LSS samples and determine their relationship with diagnostic and treatment outcomes.
