Sex Difference in the Impact of Dual Antiplatelet Therapy using Cilostazol for Secondary Stroke Prevention: A Sub-Analysis of CSPS.com.

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
aimAlthough some sex differences in stroke have been reported, differences in the effects of antiplatelet therapy for secondary stroke prevention have not been clarified.
methodsIn the Cilostazol Stroke Prevention Study combination trial, patients with high-risk, non-cardioembolic ischemic stroke between 8 and 180 days after onset treated with aspirin or clopidogrel alone were recruited and randomly assigned to receive either monotherapy or dual antiplatelet therapy (DAPT) using cilostazol and followed up for 0.5-3.5 years. The primary efficacy outcome was recurrence of ischemic stroke. The safety outcome was severe or life-threatening hemorrhage. Outcomes were analyzed by sex.
resultsA total of 1,320 male patients and 558 female patients were included. The male patients had more risk factors than the female patients. In male patients, the primary endpoint occurred at a rate of 2.0 per 100 patient-years in the DAPT group and 5.1 per 100 patient-years in the monotherapy group (hazard ratio (HR), 0.40; 95% confidence interval (CI), 0.23-0.68). In male patients, DAPT prolonged the time to recurrent stroke by 4.02-fold (95% CI, 1.63-9.96) compared with monotherapy. In female patients, the average annual event rates were 2.7 per 100 patient-years in the DAPT group and 3.3 per 100 patient-years in the monotherapy group (HR, 0.82; 95% CI, 0.37-1.84). Safety outcomes did not differ significantly in both male and female patients.
conclusionsLong-term DAPT using cilostazol reduced the recurrence of ischemic stroke and prolonged the recurrence-free time in male patients, but not in female patients.
