Overall Summary and Preponderance^a of the Incidence or Transmission of HPV Genotype-Specific Rates^b

Comparisons Between Male and Female Type-Specific Rates	Nyitray et al, 2014 [9]c	Mbulawa et al, 2012 [18]c	Liu et al, 2015 [16]d
Genotypes not tested	16	16	6
Genotypes with equal rates	9	1	26
Genotypes with M–F > F–M transmission ratesa	11	6	14
Genotypes with F–M > M–F transmission ratesa	16	29	6
Total No. genotypes	52	52	52

Abbreviations: F–M, female-to-male; HPV, human papillomavirus; M–F, male-to-female.

^aPreponderance was defined as the counts of type-specific rates favoring 1 directionality.

^bRefer to Supplementary Table 3 for type-specific rates used to determine the overall counts.

^cIncidence rates in males and females were used to infer directionality under the assumption that HPV transmission occurred between study partners. For example, a higher female HPV incidence rate would infer higher M-to-F transmission and vice-versa.

^dTransmission rates were used.
