Table 4. Presence of any one physical examination finding (capillary refill >2 secs, knee mottling, or cool extremities) as predictive of SvO₂ <60%.

N = 392	SvO₂ <60%	SvO₂ ≥60%
Any 1 physical examination finding present	24	76	Positive predictive value = 24%
No physical examination findings present	36	256	Negative predictive value = 88%
	Sensitivity = 40%	Specificity = 77%
