IQR - interquartile range; SBP - systolic blood pressure; DBP - diastolic blood pressure; MAP - mean arterial pressure; HR - heart rate; bpm - beats per minute; RR - respiratory rate; rpm - respirations per minute; T - body temperature.
Kolmogorov-Smirnov test with normal distribution (p ≥ 0.05) for septic shock and sepsis in both scenarios and Student’s t test, between septic shock and quantitative variables with a normal distribution.
Observed scenario: septic shock: mean heart rate 94.8; (standard deviation 28.2), mean body temperature 37.4 (standard deviation 1.2); sepsis: mean heart rate 106.5 (standard deviation 22.6), mean body temperature 38 (standard deviation 1.2). Verified scenario: septic shock: mean heart rate 101.6 (SD 27.7), mean body temperature 37.7 (SD 1.2); sepsis: mean heart rate 103.2 (SD 23.6), mean body temperature 37.9 (SD 1.2).
