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
purposeOral mucositis (OM) is a common side effect of radiotherapy (RT) and chemoradiotherapy (CRT) in patients with head and neck cancer (HNC). This study investigates the impact of prophylactic photobiomodulation (PBM) on OM incidence in patients with HNC undergoing RT or CRT.
methodsThis single-arm, observational study was conducted across multiple cancer centers in Brazil. Baseline assessments included clinical and radiographic dental evaluations, nutritional risk assessment via the Patient-Generated Subjective Global Assessment (PG-SGA), and HPV status determination. All patients received daily prophylactic PBM during RT. OM incidence and severity were assessed daily by a stomatologist using the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. Descriptive statistics summarized patient characteristics, and logistic regression identified potential predictors of severe OM (grade 3+).
resultsA total of 118 patients with HNC were recruited. The cumulative incidence of OM of any grade was 65.2% (95% CI 60.0-70.4%), with severe OM (Grade 3/4) observed in 28.0% of patients. Risk factors significantly associated with OM included HPV-positive tumor status (OR = 1.65, P = 0.02), concurrent CRT (OR = 1.86, P = 0.002), and nutritional risk (OR = 2.36, P = 0.004). Tumor location also influenced OM risk, with laryngeal cancers showing a lower incidence (OR = 0.72, P = 0.02).
conclusionProphylactic PBM appears effective in reducing the incidence and severity of OM among patients with HNC undergoing RT or CRT. These findings support its potential role as a preventive strategy in routine clinical care.
