Trial report in Genetics in medicine : official journal of the American College of Medical Genetics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
purposeWe evaluated the incremental prognostic value of combining the CYP2C19 poor metabolizer (PM) and ABCB1 3435 TT for adverse clinical outcomes over conventional risk factors in a percutaneous coronary intervention (PCI) cohort.
methodsWe enrolled 2,188 patients. The primary end point was a composite of death from any cause, nonfatal myocardial infarction (MI), and stroke during 1-year follow-up. The population was stratified into the following four groups: CYP2C19 EM/IM+ABCB1 3435 CC/CT, CYP2C19 EM/IM+ABCB1 3435 TT, CYP2C19 PM+ABCB1 3435 CC/CT, and CYP2C19 PM+ABCB1 3435 TT.
resultsA total of 87 (3.97%) primary end-point events occurred (64 deaths, 8 non-fatal MIs and 15 strokes). Multivariate Cox analysis indicated that CYP2C19 PM+ABCB1 3435 TT status was a significant predictor of the primary end point (hazard ratio = 4.51, 95% confidence interval (CI) = 1.92-10.58). However, addition of combined genetic status to the clinical risk model did not improve the model discrimination (C-statistic = 0.786 (95% CI = 0.734-0.837) to 0.785 (95% CI = 0.733-0.838)) or risk reclassification (categorical net reclassification improvement (0.040, P = 0.32), integrated discrimination improvement (0.021, P = 0.026)).
conclusionsIn a real-world East Asian PCI population taking clopidogrel, although the concurrent presence of CYP2C19 PM and ABCB1 TT is a strong independent predictor of adverse outcomes, the combined status of two at-risk variants does not have an incremental prognostic value beyond that of the conventional clinical risk factors.Genet Med 18 8, 833-841.
