The Tradeoff Between Shorter and Longer Courses of Dual Antiplatelet Therapy After Implantation of Newer Generation Drug-Eluting Stents.
Review in Current cardiology reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 benefit of prolonged dual antiplatelet therapy (DAPT) after implantation of drug-eluting stents (DESs) remains uncertain. In 10 randomized controlled trials (RCTs) of 31,666 predominantly low-risk patients undergoing DES implantation, shorter courses (3-12 months) of DAPT resulted in lower mortality (odds ratio [OR] 0.83, 95 % confidence interval [CI] 0.69-0.98) and major hemorrhage (OR 0.60, 95 % CI 0.48-0.75) but increased myocardial infarction (MI, OR 1.34, 95 % CI 1.04-1.73) and stent thrombosis (ST, OR 1.75, 95 % CI 1.08-2.82) than did longer courses (12-36 months) of DAPT. A risk-benefit analysis identified 3 fewer deaths and 5 fewer bleeds but 4 more MIs and 3 more STs annually for every 1000 patients treated with the shorter courses. In the predominantly low-risk population enrolled in RCTs, limiting DAPT to 3 to 12 months after DES implantation saved lives and prevented bleeding at the expense of increased ST and MI.
