Low-Level Laser and Light Therapy After Total Knee Arthroplasty Improves Postoperative Pain and Functional Outcomes: A Three-Arm Randomized Clinical Trial.
Article in Arthroplasty today, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07750912 (Photobiomodulation Therapy for Pain Control in Post-Operative Total Knee Arthroplasty Patients), which is not on this map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
Background: We examined the effect of low-level laser therapy (LLLT) and Bioptron light therapy on pain and function following primary total knee arthroplasty. Methods: A single-center, single-surgeon, prospective randomized clinical trial was performed with 3 groups of 15 patients: LLLT (804 nm), light (Bioptron; Bioptron AG, Wollerau, Switzerland), and controls. Range of motion (ROM), visual analog scale pain, opiate consumption (oxycodone in milligrams), knee swelling, and the Knee Society Score (KSS) were assessed before the surgery and on postoperative day 2, postoperative day 3, month 3, and month 12 after the operation. Results: The preoperative scores were similar between groups. A higher ROM was observed with the LLLT group at all follow-ups except at the 12-month follow-up (3-month ROM: 116.8° vs 104.0° vs 92.3°; Conclusions: In the early stages of recovery after total knee arthroplasty, LLLT and Bioptron light therapy could be helpful to control immediate and acute knee pain and swelling, reduce the need for opioids, improve ROM and functional scores, and improve recovery. Level of Evidence: Therapeutic level I.
