Comparison of functional outcomes in patients with lumbar canal stenosis with and without obesity treated with lumbar decompression surgery.
Article in Frontiers in surgery, 2026. 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
Objective: The rising prevalence of obesity has raised concerns about its impact on surgical outcomes. Obesity is a critical risk factor of low back pain and lumbar degeneration diseases, but it is still unclear whether obesity is related to lumbar surgical outcomes in the Chinese population. This study examines the influence of body mass index (BMI) on the clinical effectiveness of lumbar decompression surgery in patients with lumbar canal stenosis (LCS). Methods: 465 patients with single-segment LCS treated with lumbar decompression surgery at the LiHuiLi Hospital between April 2018 and August 2023 were enrolled in this study. Patients were divided into obesity (OB, BMI > 30 kg/m²) and non-obesity (NOB, BMI < 24 kg/m²) groups. Baseline data, operation time (OT), hospital stay (HS), Visual Analogue Scale (VAS) scores, Oswestry Disability Index (ODI), and maximum walking distance (MWD), C-reaction protein (CRP), white blood cell (WBC), complications, and reoperations were evaluated. Results: Of the total participants, 156 were categorized as OB and 309 as NOB. The NOB group exhibited significantly greater improvement in VAS scores at 1 month and ODI scores at 3 and 12 months postoperatively ( Conclusions: Obesity maybe associated with poorer functional recovery, increased complications, and prolonged recovery following lumbar decompression surgery.
