Nomogram is useful for predicting the prevalence of each patient through the scoring system without a complex formula. Because there are few studies on chronic otitis media (COM) in adults, this study aims to identify the relevant risk factors for COM in Korean adults and to build a nomogram for the risk factors. The Health Interview Survey data subset, derived from the Sixth Korean National Health and Nutrition Examination Survey (KNHANES VI), was used to evaluate the participants. Of the participants, the weighted prevalence of COM was 5.3%. Residence, earphone use, atopic dermatitis, allergic rhinitis, chronic rhinosinusitis, and subjective hearing status were identi ed as risk factors for COM. Using 6 risk factors, we propose a nomogram for COM, and use AUC to verify the discrimination of the nomogram.
