An open circle indicates not all health regions were surveyed for this province; a closed circle indicates all health regions were surveyed. We found no evidence of disproportional representation of health regions which would influence the screening outcome measures, so the subsample of health regions used in the 2003 cycle was thought to be a suitable representative of the province.
