Increasing handgrip strength via post-hypnotic suggestions with lasting effects.
Trial report in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In our study, we suggested participants to feel strong during hypnosis and tested if that affected their handgrip strength. Handgrip strength is measured via a hand dynamometer and indicates muscle strength and participants' general medical condition. In addition, we obtained subjective ratings of strength via a visual analogue scale. We developed a hypnosis intervention to increase strength and tied the feeling of strength to a post-hypnotic power anchor. Participants could activate this power anchor afterwards to feel strong again. We also had a randomized control group that read Arnold Schwarzenegger's autobiography instead of hypnosis. We tested the effect of the post-hypnotic power anchor on two experimental sessions separated by one week. Our data show that participants in the hypnosis group felt significantly stronger when they activated their post-hypnotic power anchor compared to their own baseline, both in the first and second experimental session. In addition, participants in the hypnosis group showed a significant increase in objective handgrip strength compared to their own baseline one week after the hypnosis session. We conclude that our hypnosis intervention primarily improved strength perception and secondary objective handgrip strength. Our intervention can help patients to improve their medical condition and athletes to improve their sport performance.
