Correlation Between Apolipoprotein B and Severity of Coronary Artery Stenosis in Individuals Aged 45 and Above: 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
backgroundApolipoprotein B (ApoB) is widely recognized as a biomarker significantly associated with cardiovascular risk. However, the correlation between ApoB and the severity of coronary artery anatomical stenosis (Gensini score) in individuals aged 45 and above has not been fully studied.
methodsA cross-sectional retrospective analysis was conducted, involving 818 patients who underwent coronary angiography. Fasting blood samples were collected to measure lipid parameters, including ApoB. The severity of coronary artery stenosis was assessed using the Gensini score, and patients were divided into two groups based on the median cut-off (<36 vs. ≥ 36). A multivariate regression model was used to evaluate the association between ApoB and the severity of stenosis after adjusting for potential confounding factors.
resultsCompared to the mild stenosis group (Gensini score < 36), the moderate-to-severe stenosis group (score ≥ 36) had significantly higher levels of ApoB (1.0 ± 0.3 vs. 0.9 ± 0.3 g/L) and LDL-c (p < 0.05), while HDL-c and ApoA levels were lower (p < 0.001). Multivariate regression analysis indicated that ApoB was independently associated with moderate-to-severe coronary stenosis (β = 46.1, 95% CI: 31.3-61.0 p < 0.001). Sensitivity analysis using continuous Gensini score confirmed the association (β = 22.57, 95% CI: 13.67-31.47, p < 0.0001). Dose-response analysis revealed that higher ApoB tertiles were associated with progressively higher Gensini scores (P for trend = 0.001). Stratified analysis revealed a consistent positive correlation between ApoB and Gensini scores across all clinical subgroups (all p < 0.05), with no significant interactions detected (all P for interaction > 0.05).
conclusionApoB levels are significantly positively correlated with the severity of coronary artery stenosis in the population aged ≥ 45 years, indicating its potential clinical application value in evaluation.
