In-hospital Bleeding Outcomes of Oral Anticoagulant and Dual Antiplatelet Therapy During Percutaneous Coronary Intervention: An Analysis From the Japanese Nationwide Registry.
Article in Journal of cardiovascular pharmacology, 2021. 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
abstractThe type of periprocedural antithrombotic regimen that is the safest and most effective in percutaneous coronary intervention (PCI) patients on oral anticoagulant (OAC) therapy has not been fully investigated. We aimed to retrospectively investigate the in-hospital bleeding outcomes of patients receiving OAC and antiplatelet therapies during PCI using Japanese nationwide multicenter registry data. A total of 26,938 patients who underwent PCI with OAC and antiplatelet therapies between 2016 and 2017 were included. We investigated in-hospital bleeding requiring blood transfusion, mortality, and stent thrombosis according to the antithrombotic regimens used at the time of PCI: OAC + single antiplatelet therapy (double therapy) and OAC + dual antiplatelet therapy (triple therapy). The antiplatelet agents included aspirin, clopidogrel, and prasugrel. The OAC agents included warfarin and direct OACs. Adjusting the dose of OAC or intermitting OAC before PCI was at each operator's discretion. In the study population [mean age (SD), 73.5 (9.5) years; women, 21.5%], the double therapy and triple therapy groups comprised 5546 (20.6%) and 21,392 (79.4%) patients, respectively. Bleeding requiring transfusion was not significantly different between the groups [adjusted odds ratio (aOR), 0.700; 95% confidence interval (CI), 0.420-1.160; P = 0.165] (triple therapy as a reference). Mortality was not significantly different (aOR, 1.370; 95% CI, 0.790-2.360; P = 0.258). Stent thrombosis was significantly different between the groups (aOR, 3.310; 95% CI, 1.040-10.500; P = 0.042) (triple therapy as a reference). In conclusion, for patients on OAC therapy who underwent PCI, periprocedural triple therapy may be safe with respect to in-hospital bleeding risks. However, further investigations are warranted to establish the safety and efficacy of periprocedural triple therapy.
