Endothelial Activation and Stress Index (EASIX) in migraine: association with disease subtypes and clinical characteristics.
Article in BMC neurology, 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
backgroundMigraine is a common neurovascular disorder associated with endothelial dysfunction and systemic microvascular stress. The Endothelial Activation and Stress Index (EASIX) is a novel composite biomarker that has been proposed to reflect endothelial stress and thrombo-inflammatory activity. This study aimed to investigate the association between EASIX levels and migraine subtypes and to explore its potential clinical relevance in patients with migraine with aura.
methodsThis retrospective cross-sectional study included 66 patients with migraine with aura, 99 patients with migraine without aura, and 81 age- and sex-matched healthy controls. EASIX was calculated using the formula: (lactate dehydrogenase × creatinine) / platelet count. EASIX values were compared among the study groups. Receiver operating characteristic (ROC) curve analysis was performed to assess the discriminative ability of EASIX in distinguishing patients with migraine with aura and overall migraine patients from healthy controls. Univariate logistic regression analysis was conducted to evaluate the association between EASIX levels and migraine with aura.
resultsMean EASIX values were higher in patients with migraine with aura compared to healthy controls (p = 0.048). ROC analysis demonstrated that EASIX had a modest discriminative ability to differentiate patients with migraine with aura from healthy controls (AUC = 0.58). An optimal cut-off value of 0.37 yielded a sensitivity of 66.6% and specificity of 51.8%. Logistic regression analysis revealed that higher EASIX levels were significantly associated with migraine with aura (OR: 3.35, 95% CI: 1.45-7.74, p = 0.004).
conclusionsEASIX levels were higher in patients with migraine with aura compared to healthy controls, suggesting a potential association between endothelial stress and this migraine subtype. However, its discriminative performance was limited, and EASIX should be considered as an exploratory biomarker rather than a diagnostic tool. Further prospective studies are warranted to clarify its clinical relevance.
