To obtain an appropriate index for relationships with clinical variables, we calculated five deuterogenic values: (1) Elimination rate (ER) = (lactate 15-lactate 0)/15 min; (2) lactate 15-to-lactate before ratio; (3) lactate 0-to-lactate before ratio; (4) lactate 0-to-pyruvate before ratio; and (5) lactate before-to-pyruvate before ratio.
The other deuterogenic values were nonnormally distributed.
We examined the correlations among the deuterogenic values.
