Cross sectional frequency distribution of priority among patients present in the list at an index day within each URG (A1, A2, B, C and D). Priority is shown as the integer percentage value of the respective MTBT. The frequency of patients for each URG, grouped by priority range (> 80, 0–30, 31–60, 61–80) is displayed as a raw count (a) and as a relative count (b). URGs classification is shown in Table 1.
