Fatigue Questionnaire dimension scores.

	Baseline (n = 59)	On LT4 (n = 49)		On LT3 (n = 48)		LT4 vs. LT3 (n = 47)
	Score	Change from baseline	P value	Change from baseline	P value	Change from LT4 to LT3	P value
Physical fatigue	12.2 ± 3.9	-0.5 ± 4.7	0.438	-4.0 ± 6.2	<0.001	-3.2 ± 6.1	0.001
Mental fatigue	6.6 ± 2.4	-0.4 ± 2.4	0.203	-1.8 ± 2.9	<0.001	-1.2 ± 2.7	0.004
Total fatigue	18.9 ± 5.8	-1 ± 6.6	0.303	-5.8 ± 8.7	<0.001	-4.4 ± 8.3	0.001

Data are presented as mean ± SD. Combining the scores of physical and mental fatigues produce total fatigue, with a maximum score of 33. Higher scores imply higher levels of fatigue.
