  1. 1BCS – Blantyre Coma Score
  2. 2 SMA Severe Malaria Anaemia defined as Hb <5 gm/dl or PCV<15%
  3. 3 The estimate of Pf PR was not temporally matched however it was regarded as a legitimate estimate for this peri-urban community four years later when the clinical surveillance data began.
  4. 4 Kabale is a high altitude area and while there were 3 years difference in the estimation of Pf PR and the clinical surveillance period the estimate of infection prevalence is regarded as a good approximation.
  5. 5 The investigators used a BCS ≤ 2 to describe cerebral malaria in children aged less than 5 years old and a Glasgow Coma score [32] of ≤ 8 for children 5–9 years.
