Use of a thrombelastograph platelet mapping assay for diagnosis of clopidogrel resistance: a case report.
Article in The journal of extra-corporeal technology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
A 62-year-old woman presented to the emergency department with sudden collapse, intractable ventricular fibrillation, and an inferior wall myocardial infarction (MI). An emergent cardiac catheterization showed a totally occluded right coronary artery (RCA). A bare-metal stent was placed in the stenosis, resulting in thrombolysis in myocardial infarction (TIMI)-III flow with 0% residual stenosis. Four days after stenting, the patient developed chest pain. A repeat cardiac catheterization showed a totally occluded stent. The patient was subsequently tested using a thrombelastograph (TEG) Platelet Mapping assay to exclude clopidogrel resistance. The assay confirmed the patient to be non-responsive to clopidogrel for the inhibition of platelet ADP receptors. In an attempt to increase ADP inhibition, the ADP antagonist was changed to ticlopidine. Further testing was confounded by the presence of abciximab; however, the patient has remained free of cardiac events.
