Evaluating the efficacy of photobiomodulation therapy in the management of chemotherapy-induced peripheral neuropathy: a pilot trial (NEUROLIGHT 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. It is linked to trial NCT05199389 (Evaluating the Efficacy of Photobiomodulation Therapy in the Management of Chemotherapy-induced Peripheral Neuropathy), which is not on this map.

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.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy that hinders the patient’s health-related quality of life (HRQL). Managing CIPN often requires a chemotherapy dose reduction or premature cessation of treatment. Photobiomodulation (PBM) therapy uses visible or (near)-infrared light to target tissue and stimulate cell repair processes. This trial aimed to evaluate PBM’s efficacy in managing CIPN. A randomised, controlled trial was performed with sixty cancer patients with CIPN at Jessa Hospital (Belgium). Patients underwent six PBM sessions with a fluence of 6 J/cm² (PBM-1, n = 28) or 8 J/cm² (PBM-2, n = 32). The modified Total Neuropathy Score (mTNS) and Six-Minute Walk Test (6MWT) were performed to assess the CIPN severity and mobility. Questionnaires (Numeric Rating Scale, NRS; Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity, FACT/GOG-NTX) were administered to evaluate the pain, satisfaction, and HRQL. The trial was registered at clinicaltrials.gov on the 6th of January 2022 (NCT05199389). The mTNS and 6MWT improved significantly over time (P = 0.048 and P < 0.001, respectively). No significant differences could be detected for the FACT/GOG-NTX total score, nor its neurotoxicity subscale. The pain scores improved over time (P < 0.001), with better scores in the PBM-1 group (P = 0.034). The NEUROLIGHT trial revealed a significant improvement in CIPN symptoms and mobility. PBM applied with a fluence of 6 J/cm² could be more capable of soothing the pain caused by CIPN. No improvements could be detected in HRQL. Future research is necessary to support these findings.
