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

backgroundDual antiplatelet therapy (DAPT) is recommended for ≥12 months following coronary drug-eluting stents (DES) to reduce risk of major adverse ischemic events. Randomized trials suggest an abbreviated DAPT duration (≤6 months) is adequately protective. However, these trials are individually underpowered to detect differences in rare but serious events such as stent thrombosis (ST).

objectivesWe performed a meta-analysis of published randomized trials to define the impact of abbreviated DAPT (≤6 months) on death, myocardial infarction (MI), stent thrombosis (ST), and bleeding complications compared to standard-duration DAPT (≥12 months).

methodsSeven randomized controlled trials comparing abbreviated vs. standard DAPT regimens following DES use were identified by two independent investigators. Study characteristics were reviewed and clinical endpoint data were abstracted and analyzed in aggregate using fixed and random-effects models.

resultsThe seven trials included 15,874 randomized patients. Second-generation DES were used in most patients. Compared to standard-duration DAPT, abbreviated DAPT was not associated with an increase in mortality (OR 0.93; CI: 0.73 to 1.17; P = 0.52), MI (OR 1.14; CI: 0.89 to 1.45; P = 0.30) or ST (OR 1.25; CI: 0.81 to 1.93; P = 0.31). Abbreviated DAPT was associated with significantly fewer major bleeding complications (OR 0.52; CI: 0.34 to 0.82; P = 0.005). The results were consistent between fixed and random-effects models, with no heterogeneity. Sensitivity analyses adjusting for inclusion of bare metal stents, 1st generation DES and/or abbreviated DAPT regimens of 3 months resulted in similar conclusions.

conclusionsIn a meta-analysis of >15,000 patients primarily treated with second-generation DES, abbreviated-duration DAPT (≤6 months) was associated with a significant reduction in major bleeding complications with no evidence of a significant increase in risk of death, MI or ST. Accordingly, abbreviated DAPT should be strongly considered for patients receiving second generation DES.
