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

backgroundContinuous laser acupuncture is widely used to treat chronic pain, particularly fibromyalgia. This condition causes both physical and psychological disability, leading to reduced quality of life. However, little is known about the therapeutic effects of laser acupuncture delivered at pulsed frequency. This study aimed to evaluate the effect of laser acupuncture at 36.5 Hz pulsed frequency, applied to Ryodoraku electrodiagnostic points, on pain intensity and the impact of fibromyalgia.

methods

designPilot randomized controlled clinical trial.

settingHuman Performance Research Laboratory at the university's physical therapy clinic.

participantsTwenty volunteers (aged 40-78 years) with a clinical diagnosis of fibromyalgia syndrome.

interventionsParticipants were randomly allocated into two groups. The Control Group (n = 10) received a 30-min educational lecture on fibromyalgia, while the Experimental Group (n = 10) underwent laser acupuncture treatment twice a week for three weeks.

main outcome measuresPain Numeric Rating Scale, Generalized Pain Index, Symptom Severity Scale, and Fibromyalgia Impact Questionnaire.

resultsCompared with the Control Group, the Experimental Group showed significantly lower scores on the Pain Numeric Rating Scale (p < 0.05; effect size = 2.07; power = 0.99), Generalized Pain Index (p < 0.05; effect size = 1.88; power = 0.97), Symptom Severity Scale (p < 0.05; effect size = 2.55; power = 0.99), and Fibromyalgia Impact Questionnaire (p < 0.05; effect size = 2.76; power = 0.99).

conclusionsLaser acupuncture at 36.5 Hz pulsed frequency, applied to Ryodoraku electrodiagnostic points, demonstrated beneficial effects on pain intensity and functional impact in individuals with fibromyalgia syndrome. Key Points • LASER acupuncture has a positive effect on pain intensity.. • LASER acupuncture has an impact on fibromyalgia syndrome.
