Univariate Regression Analyses for Diary Rating of Fatigue on Average FSI

Variable	R2	β	SE	t
Pre-chemotherapy
Peak diary rating	0.36	0.45	0.07	6.14 a
End diary rating	0.28	0.39	0.08	5.12 a
Average diary rating	0.52	0.70	0.08	8.46 a
Variance in diary rating	0.09	0.84	0.32	2.66 b
Post-chemotherapy
Peak diary rating	0.39	0.52	0.08	6.45 a
End diary rating	0.34	0.43	0.07	5.89 a
Average diary rating	0.54	0.72	0.08	8.80 a

Diary = Daily Diary; FSI = Fatigue Severity Inventory; R²=squared multiple correlation; β=standardized beta weight; SE=standard error.

Note: In stepwise regression models, only average diary rating was retained both pre- and post-chemotherapy.
