MLS Laser Reduce Pain in Patients with Chronic Low Back Pain.
Article in Anesthesiology and pain medicine, 2025. 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
Background: The Multiwave Locked System (MLS) has been shown to reduce inflammation and enhance biostimulation. Objectives: The aim was to investigate the effect of using MLS laser in reducing pain severity in patients with chronic back pain. Methods: This randomized double-blind study was conducted on 30 patients (15 in each group) with chronic low back pain (LBP) who were referred to Imam Khomeini Hospital and diagnosed by a physical medicine specialist based on diagnostic criteria. The intervention group was treated with MLS multiple wave laser, performed 12 times, with patients receiving laser treatment twice a week. The control group was treated with exercise therapy. Pain intensity was evaluated using the Visual Analog Scale (VAS) before treatment and 6 weeks after treatment. Pain was analyzed before and after the intervention, both within and between groups. Results: Of the 30 evaluated patients, the mean and standard deviation of age (P = 0.392) and gender (P = 0.666) were not statistically significant between the two groups. The VAS value before treatment in the intervention and control groups was 7.66 ± 1.11 and 7.73 ± 1.16, respectively (P = 0.794). After treatment, the VAS values in the MLS and control groups were 5.60 ± 1.35 and 7.73 ± 1.16, respectively. Statistical evaluation showed a statistically significant difference between the two groups (P = 0.001), and the total change in VAS values was significant (P = 0.001). Conclusions: Multiwave Locked System laser can reduce the pain severity of chronic LBP, with the reduction rate in the intervention group being significantly higher than in the exercise group.
