Caregivers' physiological responses during toddler vaccinations: associations with psychological and behavioral responses.
Article in Journal of pediatric psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study investigated biological, psychological, and behavioral aspects of caregivers' responses to toddlers' pain-related distress by measuring caregivers' high-frequency heart rate variability (HRV) responses during toddler vaccination pain and examining associations with caregivers' behavioral responses and psychological stress.
methodsParticipants included caregiver-toddler dyads (N = 194) from a longitudinal cohort-sequential study who were observed during toddlers' 12-, 18-, or 24-month routine vaccinations. Changes in caregiver HRV were analyzed using growth curve modeling. Conditional growth curve models examined associations between caregiver HRV and caregivers' concurrent behavior and psychological stress.
resultsThe unconditional growth curve model indicated a slight linear decrease in caregiver HRV (i.e., vagal withdrawal) across the 3 min post-needle (unstandardized B = -0.06, p = .049). In conditional growth curve models, higher levels of parenting stress were associated with less vagal withdrawal during the post-needle period (standardized B = 0.47, unstandardized B = 0.02, p = .003). Caregivers' behavioral responses (i.e., use of soothing and distress-promoting behaviors), state anxiety, and general anxiety symptomology were not significantly associated with HRV responses.
conclusionsCaregiver parasympathetic nervous system activity levels changed minimally from baseline to post-needle and decreased slightly across the post-needle period. Caregivers' self-reported parenting stress was associated with their parasympathetic responses to the procedure. Findings support an improved understanding of the mechanisms underlying caregivers' responses to children's pain-related distress in a naturalistic setting.
