Prognostic value of serum angiopoietin-like protein 2 in patients with acute coronary syndrome.
Article in BMC cardiovascular disorders, 2024. 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
backgroundAngiopoietin-like protein 2 (Angptl2) is a cytokine that is released to stimulate inflammation and accelerate atherogenesis. Our study sought to assess the predictive significance of serum Angptl2 in individuals diagnosed with acute coronary syndrome (ACS) and determine whether it can enhance prognostic performance beyond the GRACE risk score.
methodsWe recruited a total of 1060 patients with ACS in a consecutive manner. The levels of Angptl2 in serum were analyzed at baseline. The subjects were then followed up for 12 months to monitor the occurrence of major adverse cardiovascular events (MACE).
resultsThe level of serum Angptl2 showed a positive correlation with the GRACE score (r = 0.54, p < 0.001). Survival analysis revealed that increased levels of serum Angptl2 were associated with higher occurrence of the composite of MACE (log-rank p < 0.001) and its specific components (log-rank p = 0.011 for all-cause death, p = 0.007 for non-fatal myocardial infarction and p < 0.001 for revascularization respectively). Throughout the follow-up period, 163 instances (15.4%) of endpoint events were documented. In terms of MACE, both serum Angptl2 levels (HR: 1.178, 95% CI: 1.058-1.313, p = 0.003) and the GRACE risk score (HR: 1.181, 95% CI: 1.007-1.385, p = 0.041) emerged as significant predictors following Cox multivariate adjustment. Additionally, the addition of serum Angptl2 to the GRACE score improved the predictive capacity for prognosis [increase in area under the receiveroperating characteristic curve (AUC) from 0.740 to 0.794, p = 0.020; net reclassification improvement (NRI) = 0.401, p = 0.001; integrated discrimination improvement (IDI) = 0.022, p = 0.008].
conclusionSerum Angptl2 might be a useful prognostic biomarker and combining serum Angptl2 with the GRACE score increased the efficacy of prognosis prediction in ACS patients.
