Ceramides versus standard methods in prediction of subclinical atherosclerosis.
Article in Biomedical papers of the Medical Faculty of the University Palacky, Olomouc, Czechoslovakia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCeramides are a heterogeneous group of bioactive membrane sphingolipids that play specialized regulatory roles in cellular metabolism depending on their characteristic fatty acyl chain lengths and subcellular distribution. Ceramides have emerged as promising biomarkers for cardiovascular diseases.
methodsWithin the prospective Kardiovize study based in Brno, Czech Republic, we aimed to develop two carotid intima-media thickeness (CIMT) prediction models using available variables. One model incorporated, in addition to sex and age, conventional biomarkers (total cholesterol, triglycerides, lipid-lowering therapy), while the other included blood concentrations of selected ceramides. Lipids species were measured by a hyphenated mass spectrometry technique.
resultsA total of 139 men (mean age 61.8 ± 16.4) and 222 women (63.9 ± 14.8) were included in the present study. Both approaches yielded almost identical coefficients of determination (54.6 % vs 55.0%) with good classification abilities (weighted kappa 0.69 vs 0.71) in both models. The ceramide (d18:1/18:0) shows a strong negative association with CIMT (β = -1.39, P=0.04), while (d18:1/24:1) shows a positive association with carotid intima-media thickness (β=0.20, P=0.002).
conclusionThe tested ceramides were able to predict subclinical atherosclerosis by carotid intima-media thickness with comparable accuracy to a combination of routinely tested lipids.
