Comparisons of mean vital signs and Modified Early Warning Score between elderly and non-elderly patients in entire dataset.

	Elderly patients (n=123,671)	Non-elderly patients (n=146,285)	All patients (n=269,956)
Temperature, °C	36.6 (0.6)^*	36.6 (0.6)	36.6 (0.6)
Respiratory rate, breaths/min	19 (3)^*	18 (2)	19 (3)
Heart rate, beats/min	80 (16)^*	84 (16)	82 (16)
Systolic blood pressure, mmHg^¶	129 (24)^*	123 (21)	126 (22)
Diastolic blood pressure, mmHg^¶	66 (13)^*	71 (13)	69 (13)
Pulse pressure index	0.48 (0.09)^*	0.42 (0.08)	0.45 (0.09)
Shock index	0.64 (0.18)^*	0.70 (0.18)	0.67 (0.18)
Oxygen saturation, median (IQR), %	97 (95-98)^*	98 (96-99)	97 (95-99)
MEWS, median (IQR)	1 (1-2)^*	1 (1-2)	1 (1-2)

P-value <0.001 for comparison between elderly and non-elderly patients

^¶

Blood pressure was non-invasively measured arterial blood pressure

Pulse pressure index = (systolic blood pressure – diastolic blood pressure)/(systolic blood pressure); Shock index = systolic blood pressure/heart rate
