Aspirin plus clopidogrel versus aspirin alone in patients with mild-to-moderate stroke: A systematic review and meta-analysis.
Synthesis in Medicine, 2025. 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
backgroundStudies have shown that dual antiplatelet therapy (DAPT) is superior to aspirin monotherapy in patients with minor stroke or transient ischemic attacks. However, there is limited evidence regarding the efficacy and safety of DAPT in mild-to-moderate stroke.
methodsPubMed/MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov were searched from inception till March 2024 for published randomized controlled trials and observational studies that compared aspirin plus clopidogrel versus aspirin monotherapy in patients with mild-to-moderate stroke. R version 4.3.2 was used to calculate risk ratios (RRs) with 95% confidence intervals (95% CIs).
resultsA total of 4 studies reporting data for 15,173 patients were included. DAPT was associated with a non-significant trend of reduced risk of early neurological deterioration (END) (RR: 0.55, 95% CI: 0.28-1.05, P = .07) and recurrent ischemic stroke (RR: 0.65, 95% CI: 0.41-1.04, P = .07). The risk of recurrent hemorrhagic stroke (RR: 0.94, 95% CI: 0.47-1.86, P = .86), all-cause death (RR: 0.75, 95% CI: 0.52-1.08), or myocardial infarction (RR: 0.83, 95% CI: 0.45-1.54) was comparable across the two groups. DAPT was not associated with an increased risk of any bleeding event (RR: 0.70, 95% CI: 0.36-1.36).
conclusionDAPT demonstrated a non-significant trend toward reduced risk of END and recurrent ischemic stroke without increasing the risk of bleeding events compared to aspirin monotherapy in patients with mild to moderate stroke. Further large-scale trials are needed to confirm these potential benefits.
