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
Background: Stroke remains a major public health burden in China, and the complexity of long-term pharmacotherapy often places stroke survivors at high risk for drug-related problems (DRPs). This study aimed to identify determinants of DRPs among community-dwelling stroke patients in suburban Beijing and to propose targeted initiatives for improving rational drug use. Methods: A cross-sectional study was conducted from August 2022 to December 2024 among 481 stroke patients. Pharmacists performed face-to-face interviews to collect demographic, clinical, and drug-related information. DRPs were identified and categorized using the Pharmaceutical Care Network Europe (PCNE) Classification System (V9.1). Chi-square tests and multivariate logistic regression were used to determine factors associated with DRPs. Results: A total of 482 DRPs were identified, corresponding to 575 cause entries. The most common problems involved suboptimal treatment effectiveness and issues requiring further clarification. Patient-related causes were predominant, especially intentional underuse or non-use of drug and inappropriate timing or dosing intervals. Logistic regression showed that alcohol consumption (OR = 1.770), comorbid diabetes (OR = 1.818), depression/anxiety symptoms (OR = 1.733), and higher animal fat intake (OR = 1.711) significantly increased DRP risk. Lower income, polypharmacy, and poorer self-rated health were also associated with DRPs. Conclusion: DRPs were highly prevalent among community-dwelling stroke survivors, driven largely by modifiable behavioral and drug-use factors. Integrating PCNE-based DRP identification with pharmacist-led community interventions may help optimize drug management, enhance treatment safety and effectiveness, and support long-term secondary prevention.
