↵§§ Proportions >100% reflect situations where differences attributable to different evaluation of care within the same practice, and differences attributable to concentration of different patient groups in practices with different mean scores are opposite in direction.9 Here for example, more deprived patients are concentrated in low-scoring practices but report better care compared with more affluent patients looked after by the same practices. This is also the case for Irish White compared with British White patients.
