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.

Abstract

Background Long-term benefit of dual antiplatelet therapy (DAPT) over single antiplatelet therapy (SAPT) for the prevention of recurrent stroke has not been established in patients with intracranial arterial stenosis. We compared the efficacy and safety of DAPT with cilostazol and clopidogrel or aspirin to those of SAPT with clopidogrel or aspirin in patients with intracranial arterial stenosis, who were recruited to the Cilostazol Stroke Prevention Study for Antiplatelet Combination trial, a randomized controlled trial in high-risk Japanese patients with ischemic stroke. Methods and Results We compared the vascular and hemorrhagic events between DAPT and SAPT in patients with ischemic stroke and symptomatic or asymptomatic intracranial arterial stenosis of at least 50% in a major intracranial artery. Patients were placed in two groups: 275 were assigned to receive DAPT and 272 patients SAPT. The risks of ischemic stroke (hazard ratio [HR], 0.47; 95% CI, 0.23-0.95); and composite of stroke, myocardial infarction, and vascular death (HR, 0.48; 95% CI, 0.26-0.91) were lower in DAPT than SAPT, whereas the risk of severe or life-threatening bleeding (HR, 0.72; 95% CI, 0.12-4.30) did not differ between the 2 treatment groups. Conclusions DAPT using cilostazol was superior to SAPT with clopidogrel or aspirin for the prevention of recurrent stroke and vascular events without increasing bleeding risk among patients with intracranial arterial stenosis after stroke.
