Fig. 3From: Serum lactate poorly predicts central venous oxygen saturation in critically ill patients: a retrospective cohort studyLactate and ScvO2 (only septic shock patients) simple linear regression. ScvO2 = central venous oxygen saturation. A simple linear regression was performed with the 508 paired measurements of lactate and ScvO2 in patients diagnosed with septic shock. r2 = 0.0037 and p = 0.17. The equation for the line of best fit was ScvO2 = 72.7–0.26 (lactate)Back to article page
