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

Objectives: Patients with lumbar spinal stenosis (LSS) exhibit significantly different scoring patterns on the visual analogue scale (VAS) chart for low back pain (LP), buttock and lower limb pain (PL), and buttock and lower limb numbness (NL). This study investigated the usefulness of these preoperative scoring patterns on the VAS chart in predicting surgical outcomes in older adults undergoing LSS surgery. Methods: Time-course data from patients aged ≥65 years who underwent LSS surgery at two institutions were retrospectively assessed. All participants completed the Zurich Claudication Questionnaire and the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, which included the VAS chart, before surgery and at 6 months and 1 year postoperatively. Results: In total, 334 participants were evaluated. Patients with equal preoperative scores across all three scales showed the highest average postoperative reduction in the three VAS scores. By contrast, those with the highest preoperative VAS scores for LP or NL had the lowest reductions. Based on the multivariable analysis, the highest preoperative VAS scores for LP (relative risk: 2.1) and NL (relative risk: 2.1) were significantly associated with poor surgical improvement in older adults with LSS. Conclusions: This study demonstrated the potential clinical utility of the preoperative VAS chart in predicting surgical improvement in older patients with LSS. Patients with equal preoperative VAS scores for LP, PL, and NL were more likely to have favorable surgical outcomes, while those with the highest preoperative scores for LP or NL were at higher risk for poor outcomes.
