Serial Examination of Platelet Function Tests Might Predict Prognosis of Patients with Acute Ischemic Stroke-A Cohort Study.

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
backgroundThis study investigated whether point-of-care platelet function measurements could predict favorable outcomes in patients with acute ischemic stroke (AIS). Antiplatelet agents, such as aspirin, are known to reduce the risk of recurrent stroke by 20-30%. However, identifying nonresponders to therapy remains a clinical challenge. The study aimed to assess the prognostic value of serial Platelet Function Analyzer (PFA)-100 measurements and hematological ratios in AIS patients.
methodsA prospective cohort study was conducted on 212 AIS patients in Taiwan. Platelet function was assessed at baseline, week 2, and week 4 using PFA-100. The primary outcome was functional recovery, defined by a modified Rankin Scale (mRS) score of 0-3, at 1-month and 1-year. Subgroup analyses compared outcomes between pre- and post-aspirin administrations. Statistical analyses examined the association between changes in platelet function and clinical outcomes.
resultsDifference in collagen and epinephrine (CEPI) measurements between baseline and week 2 was associated with favorable mRS scores (
conclusionsSerial PFA-100 measurements and hematological biomarkers, specifically changes in on-treatment CEPI closure times, may help predict favorable clinical outcome in AIS patients. These findings suggest that dynamic platelet function assessment could play a role in optimizing antiplatelet therapy in AIS management.
