Effect of Clinical Manifestation and Gene on CAI

Factor	df	F ratio	P value
Clinical manifestation	3	74.52	<0.001
Gene	6	33.16	<0.001
Clinical manifestation × gene	18	16.69	<0.001

Note.—A two-way ANOVA was performed to assess the influence of clinical manifestation (mucocutaneous asymptomatic, mucosal lesions, genital warts, and cutaneous warts) and gene (E6, E7, E1, E2, E4, L1, and L2) on CAI. Both factors and their interaction show a significant effect on CAI. df, degree of freedom.
