Kidney weight (g) with respect to different treatment with A. africanus aqueous extract (EAA) and metformin in diabetic rats.

Table 2: Kidney weight (g) with respect to different treatment with A. africanus aqueous extract (EAA) and metformin in diabetic rats.

	Absolute kidney weight [g]	p-value	Relative kidney weight [%]	p-value
Neg. control	1.84 ± 0.10		0.98 ± 0.19
Nor. control	1.35 ± 0.15	0.005	0.48 ± 0.36	< 0.0001
Pos. control	1.52 ± 0.13^a	0.088	0.54 ± 0.046^a	< 0.0001
EAA 250 mg/kg	1.59 ± 0.19^aA	0.261	0.58 ± 0.05^aA	< 0.0001
EAA 500 mg/kg	1.49 ± 0.19^aA	0.060	0.56 ± 0.04^aA	< 0.0001
EAA 1000 mg/kg	1.48 ± 0.21^aA	0.031	0.56 ± 0.05^aA	< 0.0001
	F (5, 19) = 3.90; P = 0.013		F (5, 19) = 16.23; P < 0.0001

The P values indicate the difference compared to the Neg. control. Lower cases letters of the alphabet indicate the comparison between Pos. control vs. EAA (250, 500, 1000 mg/kg). Upper cases letters of the alphabet indicate the difference between the three doses of the extract (250, 500, 1000 mg/kg). Same letters indicate insignificant difference.
