Effects of different CYP2C19 genotypes on prognosis of patients complicated with atrial fibrillation taking clopidogrel after PCI.
Article in Experimental and therapeutic medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The effects of different cytochrome P450 2C19 (CYP2C19) genotypes on the prognosis of clopidogrel resistance in patients complicated with atrial fibrillation taking clopidogrel after percutaneous coronary intervention (PCI) were investigated. Eighty patients who were complicated with atrial fibrillation and treated with clopidogrel antiplatelet therapy after PCI in Meizhou Hospital Affiliated to Zhongshan University from September 2015 to January 2017 were selected, and divided into two groups according to the CYP2C19 genotype: extensive metabolism (EM) group and poor metabolism (PM) group. The related risk factors of clopidogrel resistance were determined, and the platelet aggregation rate and clopidogrel resistance rate were compared between the two groups during treatment. Non-fatal myocardial infarction and serious life-threatening complications in the two groups were observed. The increased total cholesterol level and the history of smoking and drinking were the independent risk factors of atrial fibrillation after PCI. The platelet aggregation rates in the EM group at 1, 3 and 12 months after medication were significantly lower than those in the PM group in the same period (P<0.05). The clopidogrel resistance rates in EM group before medication and at 1, 3 and 12 months after medication were higher than those in PM group in the same period (P<0.05). The onset time of non-fatal myocardial infarction in EM group was earlier than that in PM group (P<0.05), the infarct area was larger than that in PM group (P<0.05), and the left ventricular ejection fraction (EF) after onset was lower than that in PM group (P<0.05). In conclusion, the increased total cholesterol level and the history of smoking and drinking are the independent risk factors of clopidogrel resistance in patients complicated with atrial fibrillation after PCI. The incidence rates of cardiac complications are increased significantly in patients with PM CYP2C19 genotype.
