Food intake (g/day)	Statistics	G1; N. control	G2; P. control	G3; N. sativa extract	G4; Propolis extract
1st week	Mean ± SE

	t-test	—	0.00	0.00	0.00
2nd week	Mean ± SE

	0.05 = 0.648
	t-test	—	0.54	−1.58	−0.54
3rd week	Mean ± SE

	t-test

Data are represented as mean ± SE. t-test values: : significant at , : significant at , and : significant at . ANOVA analysis: within each row, means with different superscript (a, b, c, or d) are significantly different at , whereas means with the same superscript letters mean that there is no significant difference at . LSD: least significant difference; NS: nonsignificant.
