Cervical HPV alpha, beta, and gamma diversity measures^a

Diversity measure	Value for diversity measure for the following^b:
	Amerindians in the following urbanization group:			Mestizos (n = 19)	All individuals (n = 66)
	Low (n = 14)	Medium (n = 16)	High (n = 17)	Mestizos (n = 19)	All individuals (n = 66)
Median no. of HPV types per woman [range]^c	2 [1.0–4.0]	2 [1.0–4.0]	1 [1.0–4.0]	2 [1.0–6.0]	2 [1.0–6.0]
No. of high- and low-risk HPV types^d	11	12	13	18	21
No. of high-risk HPV types^d	7	8	10	11	11
No. of low-risk HPV types^d	5	5	2	7	10
Observed richness (Hill no. q = 0) [95% CI]	13.2 [8.7–17.7] (A)	13.7 [9.9–17.6] (A)	15.3 [11.5–19.2] (A)	19.7[16.0–23.4] (A)	21.0 [21.4–39.6]
Shannon diversity^e (Hill no. q = 1) [95% CI]	8.6 [6.0–11.3] (A)	9.4 [6.6–11.4] (A)	10.9 [8.2–13.7] (AB)	15.5 [11.4–19.6] (B)	12.6 [13.6–16.0]
Simpson diversity^e (Hill no. q = 2) [95% CI]	6.2 [4.1–8.4] (A)	7.0 [4.1–9.4] (AB)	8.2 [4.8–11.6] (AB)	12.4 [8.8–15.9] (B)	8.7 [8.7–10.9]
Mean Sorensen dissimilarity index^f	0.755	0.757	0.819	0.826

^{^a}

Alpha diversity analysis by urban groups was performed at a rarefaction/extrapolation of 28 women per group and at 66 women among all population (gamma diversity).

^{^b}

The presence of different capital letters within parentheses across groups indicate significant differences based on the non-overlapping of their 95% CI in brackets.

^{^c}

Median comparison was performed with Kruskall-Wallis test. Two comparisons were performed: among Amerindian groups and between Amerindians from high urbanization and mestizos; none were statistically significant.

^{^d}

High-risk HPV detected by the LiPA25 test: HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. Low-risk HPV detected by the LiPA25 test: HPV types 6, 11, 34, 40, 42, 43, 44, 53, 54, 66, 68/73, 70, and 74. Note that any incidence of 68/73 is counted as one HPV type.

^{^e}

Shannon diversity refers to exp(Shannon diversity), and Simpson diversity refers to 1/Simpson index.

^{^f}

Sorensen index of dissimilarity. Comparisons were performed with permutation test for homogeneity of multivariate dispersions, based in 99 permutations. No group was significantly different.
