Fatigue (n)	Placebo	128	182	0.032
(1: Severe, 2: Moderate, 3: Mild, 4: Slight, 5: Normal)	LC-Plasma^c	110	225
Articular pain (n)	Placebo	16	294	0.016
(1: Severe, 2: Moderate, 3: Mild, 4: Slight, 5: Normal)	LC-Plasma^d	5	332
Chill (n)	Placebo	2	308	0.516
(1: Severe, 2: Moderate, 3: Mild, 4: Slight, 5: Normal)	LC-Plasma	5	332
Lassitude (n)	Placebo	52	258	0.098

The cumulative number of days of each symptom was counted separately
^aThe cumulative days of each symptoms were compared between the placebo and LC-Plasma groups by Chi-square test
^bThe adjusted residual of the LC-Plasma group [4, 5] was calculated as 2.2
^cThe adjusted residual of the LC-Plasma group [4, 5] was calculated as 2.2
^dThe adjusted residual of the LC-Plasma group [4, 5] was calculated as 2.6
