Demographics of the Number, Mean Age, Mean BMI, and % Males for MD Patients and Non‐MD Patients

	Controls	MD Patients	Disease Controls
Number	146	48	42
Age, years	23.6 ± 13.7	33.6 ± 18.7**	41.4 ± 17.2***
BMI, kg/m2 (n)	19.1 ± 3.0 (146)	17.4 ± 3.3 (48)***	21.7 ± 3.8 (41)***
% males (n)	48.0 (70)	48.0 (23)	54.7 (23)

Mean age was significantly higher in MDs patients (33.6 ± 18.7 years old; p < 0.01) and disease controls (41.4 ± 17.2 years old; p < 0.001) than in healthy controls (23.6 ± 13.7 years old). Mean BMI was significantly lower in MDs patients (17.4 ± 3.3 kg/m²; p < 0.001) than in healthy controls (19.1 ± 3.0 kg/m²) and higher in disease controls (21.7 ± 3.8 kg/m²; p < 0.001) than in healthy controls (19.1 ± 3.0 kg/m²). Mann–Whitney U test: ^** p < 0.01; ^*** p < 0.001.

BMI = body mass index; MD = mitochondrial disorder.
