  1. Data shown as percentages and raw numbers in brackets. Significant differences (p < 0.05) existing between funding categories within rows are indicated by differing subscript letters. (No subscript letters in a row signifiy no significant differences. The presence of a subscript letter (e.g. ‘a’ in a cell indicates that it is significantly different from a cell marked with a different letter (e.g. ‘b’). If a cell has two subscript letters (e.g. ‘a,b’) then it is different from cells individually marked with each letter)
