^aThis ratio is the number of urgent suspected cancer referrals observed in the registered population divided by the number ‘expected’, based on the practice’s age–sex specific population and the age–sex specific rates for England. The unit is ‘per 100 patients’, thus the ratio for a practice at the numerical medium is 100. ⁵⁵
