3.2 The differences in laryngoscopic characteristics between benign and malignant vocal cord leukoplakia
The univariate analysis showed significant differences in the size, thickness, texture, hyperemia, anterior commissure involvement, and Zhang classification between benign and malignant vocal cord leukoplakia (P < 0.05). The results of the multivariate regression analysis showed that thickness, hyperemia and anterior commissure involvement were independent risk factors (P < 0.05). See Table 2 for detailed information.
