  1. *All nets lost since distribution irrespective of reason for loss, i.e. including nets given away for other so use.
  2. **Nets received and discarded (destroyed, thrown away) or used for other purposes than sleeping under.
  3. Attrition is reported as all cause and only due to discarding and re-purposing of nets; Integrity is based on the proportionate hole index (pHI) values (see Methods section for details).
