Clinical and imaging impact of diabetes mellitus on elderly patients with lumbar spinal stenosis: a retrospective propensity score-matched study with ≥5-year follow-up.

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: Percutaneous transforaminal endoscopic decompression (PTED) is an effective minimally invasive procedure for elderly patients with lumbar spinal stenosis (LSS). This study aimed to investigate the long-term clinical and imaging effects of diabetes mellitus (DM) in elderly patients with LSS treated with PTED. Methods: From January 2016 to December 2019, this study retrospectively reviewed 232 patients with single-level LSS who underwent PTED, comprising 45 patients with DM and 187 without DM. Propensity score matching (PSM) was conducted to balance baseline covariates between the DM and non-DM groups. Demographic data, clinical scores, radiographic parameters, complications, and reoperation rates were collected and compared. Results: After PSM, 74 patients were included, with a follow-up duration of 60-108 months. Compared with the DM group, the non-DM group demonstrated significantly greater improvement in visual analog scale scores for low back pain and leg pain, Japanese Orthopaedic Association score, and Oswestry Disability Index at 24 months postoperatively and at the last follow-up ( Conclusion: Elderly patients with LSS and DM demonstrated poorer long-term clinical outcomes after PTED. DM was associated with more severe intervertebral disc degeneration and greater fat infiltration of the multifidus muscles. Stricter postoperative glycemic control and comprehensive management of muscle function are required for elderly patients with LSS and DM.
