Downregulation and Hypermethylation of Vitamin D Receptor in Lumbar Disc Degeneration.

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
Lumbar disc degeneration (LDD) is a common musculoskeletal disorder that leads to chronic pain and functional impairment. Recent studies have suggested that the vitamin D receptor (VDR) plays a key part in regulating matrix metabolism, inflammation, and apoptosis in intervertebral discs (IVDs). The objective of this study was to examine cytokine expression and DNA methylation status of the VDR gene in blood leukocytes and lumbar disc tissues from patients with varying degrees of LDD severity. We aimed to explore correlations between VDR expression, methylation status, and clinical parameters such as pain intensity and functional disability. We conducted a prospective case-control study including 50 participants 35 LDD patients and 15 lumbar disc herniation (LDH) controls. Blood and lumbar disc tissue samples were collected for RNA and DNA extraction, followed by quantitative real-time PCR for gene expression and methylation-specific polymerase chain reaction for VDR promoter methylation analysis. Serum and nucleus pulposus (NP) VDR protein levels were measured using enzyme-linked immunosorbent assay. Clinical parameters, including pain intensity (NRS) and functional disability (ODI), were assessed. LDD patients exhibited significantly lower VDR mRNA expression in both blood leukocytes and NP tissue compared to controls (
