Biplot of CSF (Y-axis) vs plasma (X-axis) glutamine in paired samples from our hospital cohort (bilog transformation). Empty circles are the reference hospital population, and colored circles represent urea cycle disorders as indicated. The black solid line is the regression line for urea cycle disorder, the blue solid line is the regression line for the reference population (calculated based on samples with CSF glutamine levels less than 1000 μM), and the dotted line is the theoretical equality line between the CSF and plasma.
