Notes: [] RII's in parentheses indicate that results may be an artefact due to combination of population heaping and a non-linear association of immunisation coverage with wealth; a rates are not shown due to small sample size (smaller then 50) referring to the denominator, i.e. children aged 12–23 months at the time of the survey. b empty cell due to heaping (see Table 2); + 10–30% change in RII compared to the WB index; ++ >30% change in RII compared to WB index
