Correlation of physiological stress as measured by heart rate and blood pressure variability and self-reported anxiety.
Article in Research square, 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
Background: Despite lack of data, there is an assumption that anxiety symptoms correspond with a physiological stress response with decreased parasympathetic and increased sympathetic nervous system. Objective: To examine whether self-reported measures of anxiety correlate with physiological stress. Methods: We performed a secondary analysis of data collected from a 12-week clinical trial on slow breathing that examined the changes in psychological and physiological stress (n = 88). Psychological stress was assessed with PROMIS Anxiety CAT. Physiological stress was assessed by spectral analysis of heart rate including RMSSD, LF Results: Despite a decrease in mean PROMIS Anxiety from baseline to 12 weeks (-4.85 S.D. ± 5.53) from slow breathing, we found a low correlation between PROMIS Anxiety and physiological measures of stress for specific time points or changes over time. Measures of autonomic tone, including LF Conclusion: We report a lack of correlation between self-reported anxiety and physiological measures of stress despite reductions in self-reported stress after a behavioral intervention for relaxation.
