Percentages of malignant transformation in relation to the grade of dysplasia including proliferative verrucous leukoplakia within progressive and non-progressive leukoplakia (group 1 and group 2). a Percentages of malignant transformation in relation to the grade of dysplasia including proliferative verrucous leukoplakia within investigated oral and laryngeal leukoplakia. b Percentages of malignant transformation in relation to the grade of dysplasia including proliferative verrucous leukoplakia exclusively for leukoplakia located in the oral cavity. c Percentages of malignant transformation in relation to the grade of dysplasia including proliferative verrucous leukoplakia exclusively for leukoplakia located in the larynx. PVL proliferative verrucous leukoplakia. LP (group 2); non-progressing leukoplakia. LP (group 1); progressing leukoplakia
