Lumbar Belt for Nonspecific Low Back Pain: A Randomized Clinical Trial.
Trial report in JAMA network open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04701073 (Lumbar Belt Benefit Compared to the Usual Care in the Treatment of Non-specific Low Back Pain -an Interventional, Prospective, Multicenter, Randomized, Open and Controlled Study), which is not on this 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.

Abstract
Importance: Nonspecific low back pain is highly prevalent and disabling. Most current guidelines state that evidence is insufficient to recommend lumbar belts for this condition. Objective: To determine whether a soft and extensible lumbar belt reduces functional disability and pain in patients with nonspecific low back pain. Design, Setting, and Participants: This multicenter, open-label, randomized clinical trial was conducted at 17 medical centers across France from February 26, 2021, to March 28, 2024. Participants were adults with nonspecific low back pain lasting 1 to 6 months. Data were analyzed from August 7, 2024, to June 18, 2025. Interventions: Patients were randomized using an interactive web response system to wear a nonrigid lumbar belt for 12 weeks in addition to usual care or to receive usual care without a device. Main Outcomes and Measures: The primary outcome was the between-group difference in mean change in the Oswestry Disability Index (ODI) score from baseline to week 12. Outcomes were assessed at baseline, week 4, and week 12; pain was also reported weekly using online questionnaires. Results: At total of 168 patients were randomized (mean [SD] age, 49.0 [13.7] years; 101 women [60.1%]), with 86 participants in the belt group and 82 participants in the usual care group. The primary analysis included 155 patients with at least 1 postrandomization assessment (81 patients in the belt group; 74 patients in the control group). ODI improvement from baseline to week 12 was greater in the belt group (change, -10.0 [95% CI, -13.0 to -7.0] points) than in the control group (change, -5.3 [95% CI, -8.6 to -2.1] points), with a between-group difference of -4.7 (95% CI, -8.4 to -0.9) points (P = .01). Reductions in pain at rest and during activity were also greater in the belt group, with between-group differences of -8.7 (95% CI, -16.1 to -1.3) points (P = .02) and -10.0 (95% CI, -18.3 to -1.6) points (P = .02), respectively. Over 12 weeks, medication use was lower in the belt group than in the control group (41 patients [50.6%] vs 50 patients [67.6%]; P = .03). No serious device-related adverse events occurred. Conclusions and Relevance: In this randomized clinical trial, adding a nonrigid lumbar belt to usual care resulted in improved pain and functional disability in patients with nonspecific low back pain lasting 1 to 6 months. These findings suggest that lumbar belts may be considered as a nonpharmacological option for symptom management. Trial Registration: ClinicalTrials.gov Identifier: NCT04701073.
