Think FAST: Knowledge of Appropriate Action of Stroke Signs and Symptoms Among US Adults, February-March 2025.

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
backgroundThe Facial drooping, Arm weakness, Speech difficulty, Time to call 911 (FAST) mnemonic raises awareness of common stroke signs and symptoms and reinforces the urgency of activating emergency services. We examined the prevalence of knowledge of appropriate action for FAST-related stroke signs and symptoms among US adults aged ≥18 years.
methodsCross-sectional, national survey data from the National Center for Health Statistics' Rapid Survey System were collected in February-March 2025. Respondents were asked about the best action for: face drooping, arm weakness, speech difficulty, and suspected stroke. For each outcome by select sociodemographic covariates, we calculated prevalence and adjusted prevalence ratios using survey-weighted quasi-Poisson regression.
resultsAmong US adults, knowledge of appropriate action for four stroke signs and symptoms ranged from 70.8% to 83.9%. However, only 56.3% (95% CI, 54.8-57.8) identified the appropriate action for all assessed signs and symptoms. Overall, 44.6% (95% CI, 43.2-46.0) reported having heard of FAST. Compared with adults who had not heard of FAST, those who had were 31% more likely to know the appropriate action for all 4 signs and symptoms (adjusted prevalence ratio, 1.31 [95% CI, 1.24-1.39]).
conclusionsKnowledge of appropriate action for stroke signs and symptoms was high. However, only about half of adults identified the appropriate action for all signs and symptoms, suggesting gaps in stroke knowledge. Amplifying messaging, especially among adults at risk of stroke and their families, may improve knowledge of stroke signs and symptoms and the importance of calling 911, enabling early recognition and potentially decreasing morbidity and mortality.
