Thus, the following simple multiple-linear regression model without interaction effects was calculated: (1) Mean Total System Time for Severely Injured Patients = 335.88 − 0.71 Medical Specialists − 3.34 Medical Assistants − 9.57 Rotation Physicians − 0.17 General Nurses − 2.98 Surgical Assistants − 8.88 Surgical Nurses − 34.61 Radiology Assistants Please note that most of the independent staff category variables had a highly significant ( p -value < 0.001) or high significant ( p -value < 0.01) impact on the dependent variable mean total system time for severely injured patients, while only the independent variable number of general nurses had no significant impact ( p -value = 0.12) as shown in Table 5 and in Figure 4 , the Pareto chart of the standardized effects.
