Vagally mediated heart rate variability modulates the association between the perceived workload and the Stroop effect on behavioral performance.
Article in Physiological reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Vagally mediated heart rate variability (vmHRV) reflects top-down cognitive processes involved in emotion-cognition integration. Using cognitive control can be effortful and increase negative affect. However, this intrinsic affective component of cognitive control has not been well studied, and the role of vmHRV in the association between subjective experience in using cognitive control and behavioral performance remains unknown. The current study aimed to examine the relationship of vmHRV with cognitive control and perceived workload in a cognitive task. Eighty-one participants performed the Stroop interference task. Participants rated subjective workload using the NASA Task Load Index (NASA-TLX) scale for congruent and incongruent trials separately. Moreover, cognitive performance was analyzed with the ex-Gaussian model, from which the parameters μ and τ were derived to reflect sensorimotor processing and inhibitory control, respectively. Multiple regressions were used to analyze the effects of TLX change score (incongruent-congruent), vmHRV, and their interaction on the Stroop effect. Results showed that vmHRV negatively predicted the Stroop effect on τ. Importantly, vmHRV moderated the association between perceived workload and the Stroop effect on τ. Our findings highlight the role of cardiac vagal control in emotion-cognition integration and have theoretical and practical implications.
