Correlation between EASIX and short- and long-term prognosis of patients with ischemic stroke.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThis study utilized the MIMIC-IV 3.0 database to investigate the correlation between the endothelial activation and stress index (EASIX) and the short-term (30-day) and long-term (1-year) death rates of patients with ischemic stroke (IS), thus providing insights into optimizing the risk stratification and management in clinical practice.
methodsData from the MIMIC-IV 3.0 database were used. IS patients were identified by ICD codes. log2-EASIX scores were calculated based on admission platelet count, creatinine, and lactate dehydrogenase levels and patients were grouped into quartiles. The primary outcome was 30-day all - cause death rate, and the secondary was 1-year death rate. Multivariate Cox models, LASSO regression, Kaplan - Meier curves, restricted cubic splines, subgroup and interaction analyses were performed. R software was used for data cleaning and statistical analysis.
resultsThis study enrolled 3,625 acute IS patients, stratified into four groups by log₂-EASIX quartiles (Q1: -3.24 to -0.55; Q2: -0.55, 0.17]; Q3: 0.17, 1.06]; Q4: 1.06 to 7.15). Q4 had markedly higher 30-day (32.0%) and 1-year (50.7%) mortality than Q1 (15.0%, 29.3%). Fully adjusted Cox models showed Q4 vs. Q1 had elevated 30-day (HR = 1.291, 95%CI:1.035-1.610, P = 0.024) and 1-year (HR = 1.246, 95%CI:1.059-1.467, P = 0.008) mortality risks, with a significant 1-year mortality trend (P = 0.004). RCS analysis revealed nonlinear associations between EASIX and both mortalities (all P < 0.05). Bonferroni-corrected subgroup analyses found only GCS had a modifying effect (P < 0.004). ROC analysis showed EASIX had moderate predictive value (30-day AUC = 0.7545; 1-year AUC = 0.7277).
conclusionsEASIX is independently linked to short- and medium-term ACM in ICU-admitted IS patients; higher EASIX correlates with increased mortality, serving as a useful risk stratification and prognosis tool. Limited to moderate-severe ICU IS cases, prospective studies are required to verify its causal mechanisms.
