Prediction models of severe radiation-induced oral mucositis: a systematic review and meta-analysis.
Synthesis in BMC oral health, 2025. 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
backgroundRadiation-induced oral mucositis (RIOM) is a common complication in cancer survivors following radiotherapy, and numerous studies have established predictive models to evaluate the risk of severe RIOM. However, there are significant differences in the methodological quality, predictive performance, and clinical application value of these models.
objectivesThis systematic review evaluated risk prediction models for severe RIOM in cancer survivors, analyzed the limitations of the current research, and proposed recommendations for optimization, thereby providing a reference for clinical nursing staff in selecting appropriate assessment tools.
methodsThe search period spanned from the database's inception to February 2025 and included CNKI, VIP, Wanfang, Chinese Biomedical Literature Database, CINAHL, PubMed, Cochrane Library, and Embase. A meta-analysis was conducted to evaluate the incidence of severe RIOM and its predictive factors. The systematic evaluation was registered in the Platform for International Prospective Systematic Evaluation Registry (PROSPERO) database under registration CRD420250655070.
resultsA total of ten studies were included, involving 2,881 cancer survivors, encompassing 14 distinct models. Seven studies conducted internal validation, while only two studies performed external validation. Fourteen models reported the area under the Area Under Curve (AUC), which ranged from 0.657 to 0.942. The quality of the literature was assessed using the Prediction model Risk Of Bias Assessment Tool (PROBAST), revealing that nine out of the ten studies evaluated were at a high risk of bias. The meta-analysis revealed a 36% incidence of severe RIOM (95%CI = 25%-48%). Age ≥ 60 years, diabetes, smoking, and a history of periodontal disease were identified as independent risk factors for severe RIOM (P < 0.05).
conclusionsThe relevant predictive models exhibited excellent performance. However, most existing models lack external validation, limiting their extrapolation and clinical applicability. Moving forward, medical researchers should focus on developing models with exceptional predictive accuracy while minimizing the risk of bias, following standardized development guidelines.
