Updated Meta-analysis Reveals Limited Efficacy of Vitamin D Supplementation in Chronic Low Back Pain.

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
BACKGROUND/
aimChronic low back pain (CLBP) significantly reduces quality of life and increases reliance on healthcare resources. Despite many individuals opting for vitamin D supplementation to alleviate CLBP, its efficacy remains debatable. This meta-analysis aimed to evaluate the potential benefits of vitamin D supplementation in treating this condition. PATIENTS AND
methodsAdhering to PRISMA guidelines, we systematically reviewed the effectiveness of vitamin D supplementation in adults with CLBP, focusing exclusively on randomized controlled trials (RCTs). A comprehensive literature search was conducted up to May 2024 across multiple databases, including PubMed, Scopus, Cochrane Library, and Web of Science.
resultsTen RCTs meeting our inclusion criteria were analyzed. The results indicated that vitamin D supplementation did not significantly reduce pain scores compared to control groups (SMD: -0.130, 95%CI=-0.260 to 0.000; I
conclusionVitamin D supplementation does not substantially alleviate CLBP. Nevertheless, it may still be considered as part of a comprehensive treatment plan. Further research is necessary to explore its long-term effects and the underlying mechanisms that may explain the observed lack of benefit.
