These insights will identify interventions for stroke prevention that can be further explored using alternative study designs.</p><p><strong>Methods: </strong>INTERSTROKE is a large international matched case-control study of first stroke from 32 countries.

Empirical stroke research articles in the English language, published from 2014 up to 2023, and documenting PPI activity were included. Of the 18,143 original articles identified, 2824 full-text manuscripts matching from this time window were screened. Only 2% (n = 72) of these directly reported embedded PPI activity in empirical research. The majority were qualitative in design (60%) and conducted in high-income countries (96%). Only one included study originated from a developing country, where the burden of stroke is highest. Most studies (94%) provided some information about the activities carried out with their PPI partners, mainly centered on the study design (57%) and management (64%), with only 4% of studies integrating PPI across all research cycle phases from funding application to dissemination. When studies were examined for compliance with the Guidance for Reporting Involvement of Patients and the Public (GRIPP) short-form checklist, only 11% of included studies were 100% compliant. Twenty-one studies (29%) reported barriers and facilitators to including PPI in stroke research. Organization, authentic partnership, and experienced PPI representatives were common facilitators and identified barriers reflected concerns around adequate funding, time required, and diversity in perspectives. A positive reporting bias for PPI impact was observed, summarized as keeping the patient perspective central to the research process, improved care of study participants, validation of study findings, and improved communication/lay-summaries of complex research concepts.</p><p><strong>Conclusions: </strong>PPI is underutilized and inconsistently reported in current empirical stroke research.
