A comparison of screening tests for detection of high-grade cervical abnormalities in women living with HIV from Cameroon

Table 2 Distribution of results for provider-collected (Provider) or self-collected (Self) specimen tested for HPV or visual inspection after acetic acid (VIA) by severity of the cytologic interpretation for women living with HIV. Abbreviations: N+, number of positives; %+, percent positive

		HPV Testing: Provider					HPV Testing: Self					VIA
Severity of cytologic interpretation	N	N+	%+	p	p₊*	p (CD4)*	N+	%+	p	p₊*	p (CD4)*	N+	%+	p	p₊*	p (CD4)*

High-Grade	49	47	95.9				45	91.8				22	44.9

*Results on an ordinal logistic regression model for the association of the severity of the cytologic interpretation with screening test positivity adjusted for CD4 and age; p₊ is the p value for likelihood of testing positive, and p (CD4) is the p value for the likelihood of lower CD4 counts with increasing severity of the cytologic interpretation. Age was not associated with severity of cytologic interpretation
