Fig. 1From: Investigating the ability of non-invasive measures of cardiac output to detect a reduction in blood volume resulting from venesection in spontaneously breathing subjectsThis figure shows a plot of the absolute value of the inverse of the coefficient of variation plotted against the absolute value of the log-odds ratio. Variables in the upper right area of this plot showed the greatest consistancy in change resulting from venesection.
