Impact of Central Event Adjudication on the PLATO Trial Results.
Article in Reviews in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background: This study aimed to determine the impact of central adjudication of site-reported events in patients with acute coronary syndromes treated with ticagrelor or clopidogrel in addition to aspirin within the frame of indication-seeking The PLATelet Inhibition and Clinical Outcomes (PLATO) trial. Adjudication in randomized outcome-driven trials is supposed to maintain integrity by applying uniform rules for the quality assessment of clinical events. Some preliminary data suggest an imbalance between central and site diagnoses in PLATO. We gained access to the Food and Drug Administration (FDA)-issued adjudication dataset and analyzed the evidence. Methods: Death, myocardial infarction (MI), stroke/ transient ischemic attack (TIA), bleeding, arterial thrombotic events, and cardiac ischemic events underwent central adjudication. We assessed geography, timing, impact of disagreements, and primary endpoint composition. Results: Among 18,624 trial enrollees, 10,704 central adjudications occurred across 7171 patients in 43 countries. There were 938 deaths, 2751 cases of MI, 359 strokes/TIAs, 2680 cardiac events, 130 thrombotic events, and 3782 bleeding events. The match occurred for 5451 events, while mismatches favoring clopidogrel (n = 2535) or ticagrelor (n = 2706) ( Conclusion: Central adjudication in the PLATO trial was delayed and impacted the primary endpoint by inflating the ticagrelor benefit, resulting in drug approval. The regulatory authorities should consider independent audits when unblinding is suspected in the indication-seeking clinical trials.
