Negative Emotional Influences on Pressure Pain Thresholds: Findings from a Quasi-Randomized Controlled Trial.
Article in Journal of pain research, 2026. 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
Objective: Human emotions could affect pain perception, but knowledge from well-powered experiments about how different emotions affect pressure pain thresholds (PPTs) in pain-free individuals are missing. The aim of this quasi-randomized control trial was to investigate the effect of different emotional states on PPTs in four different body locations (upper, right m. trapezius; upper, left m. trapezius; right m. tibialis anterior; left m. tibialis anterior). Methods: Pain-free participants (n = 152) were assigned to four different emotional states (negative n = 38; positive n = 38; distraction control n = 38; control n = 38). Baseline PPTs in each group were measured after a neutral video clip following emotional state induction with video clips (negative; positive; distraction control; control). PPTs were again measured after emotion induction. Results: The main finding was that negative emotion induction significantly lowered PPTs in the m. trapezius and m. tibialis anterior on the left side of the body after correction for multiple comparisons. PPTs were also significantly lower in the left m. tibialis anterior in the distraction control group. No other significant differences in PPT levels were found. Conclusion: Negative emotions, but not positive emotions, could significantly lower PPTs in the left m. trapezius and the left m. tibialis anterior in healthy individuals. A practical implication may be that negative emotions might negatively affect pain states through descending pain modulation.
