Geometric Mean Levels of and Percentage Change in Mitochondrial Enzymes From Baseline to End of External Beam Radiation Treatment (EBRT) by Fatigue Group.

	HF (n = 12)				LF (n = 10)
Mitochondrial enzyme	Baseline	Completion	Percentage Change	Direction of Change	Baseline	Completion	Percentage Change	Direction of Change
Complex I	0.892	1.016	13.87	↑	1.395	0.901	−35.44	↓
Complex II	0.004	0.010	125.68	↑	0.002	0.002	−1.17	↓
Complex III	1.371	1.993	45.39	↑	4.535	2.175	−52.05	↓
Complex IV	0.480	0.581	21.01	↑	0.705	0.598	−15.25	↓
MnSOD	1,315.1	1,276.7	−2.92	↓	1,097.6	1,110.4	1.17	↑

Note. Values for Complexes I–IV are expressed as geometric mean absorbance at 600 nm. MnSOD values are expressed as geometric mean concentration (ng/ml). HF = high fatigue; LF = low fatigue; MnSOD = manganese superoxide dismutase. p Values >.05 for all measures.
