Clinical Outcomes of Ticagrelor versus Clopidogrel in Patients with Chronic Kidney Disease and Acute Myocardial Infarction: A Real-World Cohort Study.
Article in Cardiorenal medicine, 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
introductionChronic kidney disease (CKD) is a major risk factor for cardiovascular morbidity and mortality, particularly in patients with acute myocardial infarction (AMI). Dual antiplatelet therapy is essential for secondary prevention in AMI, but the optimal P2Y12 inhibitor in CKD patients remains unclear. While ticagrelor has demonstrated superior cardiovascular outcomes compared to clopidogrel in the general population, its safety and efficacy in advanced CKD are not well established.
methodsThis retrospective cohort study analyzed data from the Chang Gung Research Database (CGRD) to compare ticagrelor and clopidogrel in CKD stage III-V patients hospitalized with AMI between 2001 and 2020. Inverse probability of treatment weighting was applied to balance baseline characteristics. Clinical outcomes, including recurrent AMI, ischemic stroke, cardiovascular death, major bleeding events, and all-cause mortality, were evaluated using Cox proportional hazards models and competing risk analysis.
resultsAmong 3,461 patients (ticagrelor: 704, clopidogrel: 2,757), ticagrelor was associated with a significantly lower risk of all-cause mortality (HR 0.694, 95% CI 0.539-0.894, p = 0.047), with no significant differences in recurrent AMI, ischemic stroke, cardiovascular death, or major bleeding events.
conclusionsIn CKD patients with AMI, ticagrelor was associated with reduced all-cause mortality compared to clopidogrel, without an increased risk of major bleeding. These findings highlight the need for further prospective studies to confirm ticagrelor's benefits and inform optimal antiplatelet strategies in this high-risk population.
