The association between bone turnover biomarkers and the severity of white matter hyperintensities.

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: Bone health may be associated with cerebral small vessel disease. This study aims to explore the correlation between bone turnover biomarkers (BTMs) and parathyroid hormone (PTH) with the severity of white matter hyperintensities (WMH). Materials and methods: We retrospectively analyzed 213 inpatients from the Neurology Department of Beijing Jishuitan Hospital between June 2021 and May 2022. The WMH burden was assessed semi-quantitatively using the age-related white matter changes scale and the Fazekas scale, with the latter separately evaluating periventricular WMH (PWMH) and deep WMH (DWMH). Participants were categorized into two groups based on WMH severity. Binary logistic regression was performed to investigate the relationship, and subgroup analyses were conducted across subgroups stratified by sex, hypertension, and diabetes. Results: Patients with severe WMH, PWMH, and DWMH had significantly higher β-carboxy-terminal cross-linked telopeptide of type 1 collagen (β-CTX) and PTH levels compared to those in the mild groups. After adjusting for confounding factors, elevated β-CTX levels remained associated with severe WMH (OR: 4.44, 95% CI: 1.33-14.81) and severe PWMH (OR: 6.37, 95% CI: 1.80-22.47), while increased PTH levels were associated with severe DWMH (OR: 1.02, 95% CI: 1.01-1.05). Subgroup analysis showed a significant relationship between PTH and the severity of WMH and PWMH in patients with diabetes ( Conclusion: β-CTX was independently linked to WMH/PWMH severity, and PTH to DWMH severity, pointing to a possible bone-cerebrovascular axis. Larger prospective and interventional studies should confirm these markers as potential CSVD biomarkers and treatment targets.
