Effectiveness of low-level laser therapy in the rehabilitation of knee meniscus injuries: a randomized, double-blind, placebo-controlled trial.
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. 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
To evaluate the effectiveness of low-level laser therapy (LLLT) as an adjunct to rehabilitation in reducing pain and improving knee function in adults with MRI-confirmed meniscus injuries. In this randomized, double-blind, placebo-controlled trial, 40 adults with unilateral meniscus injuries were assigned to either an LLLT group or a placebo group. All participants received a standardized rehabilitation program over six weeks. The primary outcome was pain intensity measured using a visual analogue scale (VAS). Secondary outcomes included knee function (Lysholm score), range of motion (ROM), and physical performance tests. Both groups showed significant improvements; however, the LLLT group demonstrated greater reductions in pain and improvements in function, mobility, and ROM compared with the control group (p < 0.01 for all outcomes). The magnitude of improvement exceeded clinically meaningful thresholds, particularly for pain reduction and functional gains. Adjunctive LLLT was associated with greater improvements in pain and functional outcomes compared with rehabilitation alone. LLLT appears to be a safe and potentially effective complementary modality in the conservative management of meniscal injuries.
