1 · What the graph read from 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.

2 · The registry

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

Patients with lesser degrees of platelet inhibition in response to clopidogrel appear to be at increased risk for recurrent ischemic events. Cytochrome P450 (CYP) polymorphisms have been proposed as possible mechanisms for nonresponsiveness to clopidogrel. Published data on the association between CYP2C19*2 polymorphism and atherothrombotic events are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. A total of eight prospective cohort studies including 2,345 patients carrying CYP2C19*2 variant allele and 5,935 cases with the wild-type genotype were included in this meta-analysis. Overall, borderline statistically significantly elevated risk of adverse clinical events was associated with genotyping 681G>A polymorphism (for AA + GA vs. GG: OR, 1.46; 95% CI, 1.01 to 2.13; P = 0.05). The summary odds ratio showed a significant association between the CYP2C19*2 polymorphism and an increased risk of cardiac mortality in the follow-up period (OR, 2.07; 95% CI, 1.22 to 3.52; P = 0.007). When studies evaluating myocardial infarction, stent thrombosis, and ischemic stroke, the presence of the variant allele was associated with significantly increased risks of recurrent atherothrombotic events. In summary, this meta-analysis indicated that CYP2C19*2 carrier status is significantly associated with an increased risk of adverse cardiovascular events.
