1 · What the graph read from it

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.

2 · The registry

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

Excessive pain during medical procedures is a pervasive health challenge. This study tested the (additive) analgesic efficacy of combining hypnotic analgesia and virtual reality (VR) pain distraction. A single blind, randomized, and controlled trial was used to study 205 undergraduate volunteers aged 18 to 20. The individual and combined effects of hypnotic analgesia (H) and VR distraction on experimentally induced acute thermal pain were examined using a 2 X 2, between-groups parallel design (4 groups total). Participants in groups that received hypnosis remained hypnotized during the test phase pain stimulus. The main outcome measure was "worst pain" ratings. Hypnosis reduced acute pain even for people who scored low on hypnotizability. As predicted, H+ VR was significantly more effective than VR distraction alone. However, H+ VR was not significantly more effective than hypnotic analgesia alone. Being hypnotized during thermal pain enhanced VR distraction analgesia.
