Comparative study of photodynamic therapy with LED and probiotics in the treatment of halitosis: protocol for a randomised controlled clinical trial.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06583720 (Comparative Study Between Photodynamic Therapy with LED Associated with Probiotics in the Treatment of Halitosis - Controlled Randomized Clinical Trial), 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.
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
introductionHalitosis is a term that defines any unpleasant odour smell originating from the oral cavity and may have a local or systemic origin. This project aims to determine the effectiveness of treatment involving antimicrobial photodynamic therapy (aPDT) combined with treatment using probiotics at reducing halitosis. METHODS AND ANALYSIS: 92 individuals from 18 to 60 years of age with a diagnosis of halitosis (sulfide≥112 ppb, gas chromatography) will be selected. The participants will be randomly allocated to four groups (n=23). Group 1 (control): brushing, dental floss and tongue scraper; group 2: brushing, dental floss, tongue scraper and aPDT with blue Light Emitting Diode (LED) +annatto; group 3: brushing, dental floss, tongue scraper and aPDT with blue Light Emitting Diode (LED) +annatto and probiotic lozenges containing ETHICS AND DISSEMINATION: This protocol has been approved by the Human Research Ethics Committee of Nove de Julho University (certificate number: 82830524.6.0000.5511; approval date: 2 October 2024). Participants will agree to take part in the study by signing an informed consent form. The findings will be published in a peer-reviewed journal. The collected data will be available in the OSF data repository. TRIAL REGISTRATION NUMBER: NCT06583720.
