1 · What the graph read from it

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.

2 · The registry

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

backgroundHyperlipidemia is a major risk factor for coronary atherosclerotic heart disease (CAHD). However, conventional lipid profiling fails to fully reflect the complexity of lipid metabolism. Furthermore, while lipidomics has identified numerous complex lipids as biomarkers, the role of their fundamental constituents-serum fatty acids-remains less explored in CAHD. In this study, we performed detailed profiling of serum fatty acid species to explore their utility in improving the identification and management of lipid disorders specifically within the CAHD population, an approach whose clinical value in this context remains underexplored.

methodsThe study analyzed serum fatty acid profiles in three CAHD cohorts: a training cohort (n = 432) and two external validation cohorts (n = 1302 and n = 1458). Serum samples were collected during initial and subsequent hospitalizations. A total of 39 fatty acids were quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Multivariate analyses were conducted to identify fatty acids with diagnostic relevance, followed by model development and external validation.

resultsIn CAHD patients, several fatty acids were significantly correlated with total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein B (Apo B). Among these, esterified linoleic acid demonstrated a strong correlation with lipid biomarker (r > 0.69, p < 0.001). Logistic regression analysis identified esterified oleic acid (OR = 37.80, p < 0.001) and linoleic acid (OR = 10.74, p < 0.001) as independent significant risk factors for hyperlipidemia. The combined model incorporating these fatty acids demonstrated an AUC exceeding 0.94 (95% CI: 0.93-0.95) in both training and validation cohorts, with sensitivity and specificity exceeding 85.6% and 81.0%, respectively. Notably, during statin therapy, linoleic acid decreased significantly and was associated with favorable lipid-lowering effects, comparable to the rate of change in TC, with no significant difference.

conclusionsEsterified linoleic acid (C18:2 n6) and oleic acid (C18:1 n9) were identified as key serum biomarkers for hyperlipidemia in CAHD patients, and their combination yielded the best diagnostic performance. Moreover, C18:2 n6 decreased during statin therapy and may serve as a useful marker for monitoring treatment response.
