LDL-C/HDL-C ratio as a predictor of atherosclerosis in the Japanese population: insights from a cross-sectional study.

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
backgroundAtherosclerosis is a major contributor to cardiovascular disease, and dyslipidemia, particularly low-density lipoprotein cholesterol (LDL-C)/ high-density lipoprotein cholesterol (HDL-C) ratio, plays a critical role in its pathogenesis. Although extensive research has been conducted in Western populations, the relationship between LDL-C/HDL-C ratio and atherosclerosis in the Japanese population remains underexplored. The aim of this study was to investigate the association between LDL-C/HDL-C ratio and atherosclerosis, as measured by brachial-ankle pulse wave velocity (baPWV), in a Japanese cohort.
methodsThis secondary analysis used data from a cross-sectional study involving 912 participants. LDL-C/HDL-C ratio was calculated from fasting blood samples and baPWV was used to assess atherosclerosis. Univariate and multivariate analyses were performed to evaluate the association between LDL-C/HDL-C ratio and baPWV, adjusting for age, sex, body mass index (BMI), and other potential confounders. Subgroup analyses were performed to explore variations by demographic and clinical factors.
resultsThe mean age of the study population was 51.1 years, and 64.9% were male. Significant differences were observed across LDL-C/HDL-C ratio tertiles for age, sex, BMI, blood pressure, liver enzymes, lipid profiles and lifestyle factors (p < 0.001 for most). Univariate analyses showed strong associations between atherosclerosis and age, sex, BMI, blood pressure, liver function markers, metabolic factors and lifestyle behaviours (p < 0.001 for most). Multivariate linear regression models were used to examine the association between LDL-C/HDL-C ratio and baPWV, adjusting for factors such as age, sex, BMI, and other metabolic variables. Subgroup analyses showed significant associations between LDL-C/HDL-C ratio and baPWV in women (p = 0.036), participants aged < 55 years (p = 0.009), and those with BMI < 25 kg/m² (p = 0.044). No significant interactions were observed between subgroups (p for interaction > 0.05).
conclusionsLDL-C/HDL-C ratio is significantly associated with atherosclerosis in the Japanese population, with varying strength in different demographic and clinical subgroups. These findings highlight the importance of LDL-C/HDL-C ratio as a predictor of atherosclerosis and underscore the need for targeted interventions to manage cardiovascular risk in this population.
