  1. aThe number and prevalence estimates are adjusted based on the assumption that the prevalence of disability was the same among children who did and didn’t attend the examination camp. The denominator used to calculate the prevalence of impairments is the total number of children (338,235) living in the 8 traditional areas included in the study
  2. bThe prevalence range is based on sensitivity analysis assuming the proportion of non-attenders having an impairment/epilepsy was ±10% of the actual proportion among attenders
  3. cPer million total population of all ages, not population of children
  4. dIt was not possible to conduct Pure Tone Audiometry on 40% of children aged 5+ years and Ottoacoustic Emmission test results were used for those children
