*a**Median total (predicted) payments for a 7000 patient list were £718 480 in 2013–2014 and £740 530 in 2014–2015. In each cell, values in the first line are for 2013–2014 and in the second line for 2014–2015. Numbers inside the parentheses are the percentage changes to total payments. Calculations assumed a reference point of the total payments per patient being at the median (£102.64 in 2013–2014 and £105.79 in 2014–2015).**Equations used in the calculations:*^{28}*1. Change in payment (amounts)*=*list size*×*median total payment per patient*×*[e*^{(β coefficient × difference between median and quartile values)}−*1].**2.
