Bivariate correlations for patients in the mut (methylmalonyl-coenzyme A) subgroup with dual-energy X-ray absorptiometry data are depicted between REE (resting energy expenditure) per kilogram of FFM (fat-free mass) and creatinine clearance (mL · min−1 · 1.73 m−2; n = 19), total protein intake (g · kg−1 · d−1; n = 19), and height-for-age z score (age: ≤20 y; n = 15). Pearson's correlation coefficients and P values for each correlation are shown.

Measured and predicted resting energy expenditure (REE) and total kilocalories provided are presented in kilocalories per day for the entire patient population. A: Measured REE compared with predicted REE based on the Schofield equation (17) and total kilocalories per day provided to patients ≤18 y of age (n = 22). B: The same variables for patients >18 y of age in which predicted REE is calculated by the Harris-Benedict equation (20) (n = 7). Measured REE was lower than predicted by any of the equations as well as from the actual total calories provided in both age groups (P < 0.001 for both paired comparisons between measured REE and the values derived from each of the predictive equations as well as measured REE compared with total daily kilocalories provided, paired t test). Statistical analyses were performed by using SPSS version 17 (SPSS Inc, Chicago, IL).

A: Weight-, height-, and BMI-for-age z scores for patients in the mut (methylmalonyl-coenzyme A) group of methylmalonic acidemia aged ≤20 y (n = 18) are depicted. Boxes represent the middle 50% of all cases per variable, whereas the remaining 50% is contained between the box and whiskers on each side. The single line inside each box represents the median of the entire data set. The location of this line suggests the skewness in the distribution, when noticeably shifted away from the center, as is the case particularly for the BMI-for-age z score in the mut subgroup. B: Percentage fat mass in males and females aged ≤18 y with the mut subtype of methylmalonic acidemia is depicted. Percentage fat mass was significantly higher in female patients with the mut subtype than in males (P < 0.001, t test). Female patients also had significantly higher percentage fat mass compared with the highest value for white females in the reference population [27.6 ± 6.1% (n = 46), depicted as solid lines ± dotted lines (P < 0.001, t test)] (14). Statistical analyses were performed by using SPSS version 17 (SPSS Inc, Chicago, IL).
