c The analysis excluded 39 survey responses because the girls who were vaccinated were not 10 years old, as required by the vaccination strategy.
d The analysis excluded 192 survey responses because either the girls who were vaccinated were not 10 years old, as required by the vaccination strategy, or the girl was actually vaccinated in the first year of the programme rather than the second.
e Systematic random sampling from a complete census of all eligible households was used in the second year.
f There were 660 girls in each of three urban blocks.
