Autonomic Disequilibrium at Rest in Autistic Children and Adults.
Article in Applied psychophysiology and biofeedback, 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
Autism Spectrum Disorder (ASD) symptoms have been proposed to be linked to Autonomic Nervous System (ANS) atypical functioning, in particular sympathetic hyper-arousal and parasympathetic under-activation. The objective of this study was to characterize autonomic functioning at rest in autistic and neurotypical children and adults. To characterize several aspects of autonomic functioning, we recorded simultaneously pupil diameter, heart rate and electrodermal activity during 5 min of rest in 44 children (6-12 years old, 22 autistic) and 42 adults (19-52 years old, 21 autistic). Several parameters allowed to characterize tonic and phasic indices of sympathetic and parasympathetic systems at rest. Autistic children exhibited the expected pattern of parasympathetic under-activation at rest compared to their typically developing (TD) peers, and with a tendency for a higher phasic sympathetic activity. Adults exhibited a reverse autonomic pattern, with autistic individuals showing higher sympathetic tonus and lower sympathetic phasic activity than their TD peers. In conclusion, we observed an autonomic disequilibrium at rest both in autistic children and adults, but with opposite patterns that could reflect adaptive compensation mechanisms during maturation. This disequilibrium in autistic children would switch from excessive phasic components to excessive tonic components in adults, possibly subtended by an atypical locus coeruleus functioning.
