Clinical observational studies of potential participants' current negative affect status for a clinical study of stem cell therapy for ischemic stroke: study protocol.
Article in Frontiers in neurology, 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
Introduction: The number of clinical research projects on stem cell therapy for stroke has increased annually with the rapid development of stem cells and regenerative medicine technologies. Some evidence indicates that negative emotions can affect the recruitment, compliance, retention, satisfaction, and even treatment outcomes of participants in clinical research. However, knowledge is insufficient regarding patients' negative emotions associated with their participation in potential stem cell clinical research studies. Therefore, the study aims to investigate the negative emotions and main influencing factors for potential participants in clinical research on stem cell therapy for stroke. Methods: This study protocol follows the Strengthening the Reporting of Observational Studies in Epidemiology Good Practice for Reporting Observational Studies. The questionnaire for this study will include 59 questions for potential participants regarding (1) their demographic characteristics, and (2) their levels of anxiety, depression, social support, general self-efficacy, and self-perceived burden. Discussion: This study's main strength is that it will contribute evidence on key predictors of negative affectivity in potential participants undergoing clinical trials of stem cell therapy for stroke. The results will support stem cell clinical center researchers in intervening in potential participants' negative emotions, which is important for clinical research managers and policymakers worldwide. Conclusion: The study protocol developed in this study was validated through a rigorous development process, demonstrating scientific validity for negative affect evaluation in stem cell clinical research. This instrument provides clinicians with a standardized assessment protocol to monitor treatment-emergent emotional distress during experimental interventions, showing particular promise in identifying early psychological risks associated with novel biological therapies.
