Effectiveness of GV20-based wearable low-level laser acupoint therapy for pain on head.
Trial report in Lasers in medical science, 2026. 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
The effectiveness of GV20-based Wearable Low-level Laser Acupoint Therapy for pain on right temporal head was investigated. The study was designed as a triple-blinded, randomized controlled clinical trial. The deep pressure pain targeted by 300g monofilament and Visual Analog Scale (VAS, 0-10) scores on right temporal head were assessed were randomly assigned to wearable LLLAT (650 nm, 5 mW, 30 min, about 9 joule each acupoint) on Baihui (GV20) with four Sishencong (EX-HN1) or sham group (n=24 vs 24). The mean VAS pain scores in wearable LLLAT group after GV20 with EX-HN1 acupoint treatment were significantly decreased comparing with sham group. This trial suggested that wearable Low-level Laser Acupoint Therapy 650 nm 5 mW for 30 min each acupoint simultaneously could effectively reduce deep pressure pain on temporal head.
