Table 6.

Additional CIN2⁺ by ECC, given the number of lesion-directed ectocervical biopsies

Number of Lesion-Directed Ectocervical Biopsies	CIN2⁺ on Ectocervical Biopsy (n;% n/N)	Additional CIN2⁺ on ECC (n;% n/N)	P-value
Overall N = 181

0	0 (0.0)	26 (14.4)	<0.05
1	38 (21.0)	14 (7.7)
2	50 (27.6)	9 (5.0)
3	53 (29.3)	8 (4.4)
4	54 (29.8)	7 (3.9)

Note that examinations with more than one lesion-directed ectocervical biopsy are represented more than once in this table; hence the total column count for the cumulative CIN2⁺ detected on lesion-directed ectocervical biopsies exceeds the number of total examinations (N > 181). Additional CIN2⁺ on ECC when the number of lesion-directed ectocervical biopsy was 0 is squivalent to the overall CIN2⁺ yield on ECC, as previously presented in Table 2. Chi-Square (X²) analysis for trend was conducted and does not include the aggregate rate of 26/181 in the first row.
