Risk Factors and Predictive Model for Otitis Media With Effusion After Radiotherapy in Nasopharyngeal Carcinoma: A Retrospective Study.
Article in World journal of otorhinolaryngology - head and neck surgery, 2026. 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
Objective: To investigate the impact of different radiation fields on the risk of otitis media with effusion (OME) in nasopharyngeal carcinoma (NPC) patients and to develop a nomogram to identify high-risk patients after radiotherapy. Methods: Clinical data were collected from 170 NPC patients who underwent radiotherapy at Peking Union Medical College Hospital (January 2016-December 2021, development group) and 73 patients (January 2022-June 2024, validation group). Multivariate logistic regression analyses were used to identify risk factors for OME, and a nomogram was constructed based on these findings. Results: Multivariate analysis revealed that gender, invaded eustachian tube, and radiation to the parotid and periauricular field and parapharyngeal space were independent risk factors for OME. The nomogram demonstrated good discrimination, with AUC values of 0.813 (development group) and 0.798 (validation group). Calibration was confirmed with Hosmer-Lemeshow test results ( Conclusion: In conclusion, radiation fields are significant risk factors for OME in NPC patients. The developed nomogram enables early identification of high-risk patients, supporting timely intervention.
