¹Method 1 - using BNDIP (2008) P1 child data:– schools within the respective Health Board ranked in descending order by proportion of children with caries experience within respective schools.
²Method 2 - using local SIMD of child home postcode:– schools within the respective Health Board ranked in descending order by proportion of children with home postcodes in the most deprived local quintile (local SIMD1 2009).
³Method 3 - using BNDIP (2008) P1 child data:– schools ranked across Scotland in descending order by proportion of children with caries experience.
⁴Method 4 - using national SIMD of child home postcode:– schools ranked across Scotland in descending order by proportion of children with home postcodes in the most deprived quintile (national SIMD1 2009).
⁵The island Health Boards of Orkney, Shetland and Western Isles have no national SIMD1 datazones and therefore do not feature in analysis relating the methods or definitions of risk using national SIMD1. SIMD data for WI was incomplete preventing analysis by child SIMD.
