  1. aTotal numbers for sex and age differs because sex is available for every human genotype in blood meals, whereas age requires matching to an enrolled participant. No. of At-risk nights was calculated as the sum of the number of collection nights participants in each demographic category slept in the household
  2. P-value in Bold indicates that this demographic group contributed more or less blood meals than expected
  3. Males contributed more blood meals than expected in proportion to their availability in the population. This was especially true for age group 31–75 years old. Logistic regression analysis revealed the same associations
