From: Clustering patterns of human papillomavirus infections among HIV-positive women in Kenya
Observed versus Expected occurrence for 2-way combinations of 44 HPV types, HIV-positive women in Kenya. Plus signs represent occurrences of HPV pairs. HPV pairs located in the upper triangle indicate positive clustering, while those located in the lower triangle represent negative clustering between the HPV types involved. None of the p-values for joint HPV infections was significant at the chosen significance level of 0.00005. No significant associations emerged even when considering a less conservative level, p < 0.01.
