Table 3.

The percentage of mtDNA common deletion in the model including diagnosis, sex, age, and pH

	Least square means, % mthNA common deletion	SE	Unadjusted means, % mthNA common deletion
A Diagnosis
Bipolar disorder	0.126	0.019	0.115
Control	0.103	0.019	0.105
Schizophrenia	0.092	0.022	0.049
B Sex
Female	0.127	0.020	0.144
Male	0.079	0.011	0.075

The age variable was significant in the model (p = 0.002) while the diagnosis was not significant (A). Differences between sex (B) were significant (p = 0.03), female subjects having more mtDNA common deletion in PFC following adjustments for other effects. SE, standard error.
