Table 3. Wilcoxon signed rank test of elevation of physiologic parameters after TAE for blunt splenic injuries.

Items	Mean difference	95% CI	p-value
Systolic pressure (mmHg)
Immediate elevation	12.7 ± 30.3	(0.5, 25.0)	0.069
Elevation 24 hours later	28.2 ± 40.5	(11.9, 44.6)	0.001
Pulse pressure (mmHg)
Immediate elevation	8.7 ± 31.8	(–4.1, 21.6)	0.322
Elevation 24 hours later	17.4 ± 31.1	(4.8, 30.0)	0.006
Pulse rate (beats per minute)
Immediate reduction	0.6 ± 16.6	(–6.1, 7.3)	0.919
Reduction 24 hours later	5.2 ± 20.6	(–3.2, 13.5)	0.319

TAE = transcatheter arterial embolization; CI = confidence interval.
