Comparison of intensive care unit (ICU) mortality and in-hospital mortality between Specialised Relative Insulin Nutrition Tables (SPRINT) and retrospective patients for several iterations of the patient selection procedure detailed in Figure 1. The top row of plots shows ICU mortality, and the bottom row of plots shows hospital mortality. The retrospective mortality average is shown by the horizontal line, and mortality since initiation of SPRINT is shown by the variable line. The horizontal axis represents the total number of patients treated with the SPRINT protocol. The plots are grouped by length of ICU stay (LOS). The spread of lines results from the random patient selection process.
