Fig. 5From: Effect of Ringer’s acetate in different doses on plasma volume in rat models of hypovolemiaPlasma oncotic pressure at 60 min after completion of resuscitation. Differences in dose-dependent decrease in plasma oncotic pressure between the two groups were analyzed by comparing the slope of the dose–response curves as calculated by linear regression. (P < 0.001 for the difference in slope using linear regression with an interaction term)Back to article page
