Table 4 Serum CRP levels between the two groups on days 1, 3, 5, and 7

Day	Casein protein group (n = 17)		Egg white powder group (n = 17)		p value (between groups)
Day	Biochemical values	p value (compared to day 1)	Biochemical values	p value (compared to day 1)	p value (between groups)
CRP (mg %)
Day 1	7.2 ± 1.4		7.3 ± 1.3		0.96
Day 3	5.2 ± 0.9^a	0.03	5.6 ± 1.1	0.16	0.74
