Two-way ANOVA
Protein level (P)	p < 0.00	p < 0.00	p < 0.00	p < 0.00
Kombucha (K)	p < 0.00	p < 0.00	p < 0.00	p < 0.00
P × K (Interaction)	p < 0.00	p < 0.58	p < 0.00	p < 0.00

The values are presented as the mean ± SD.
Significant differences (p < 0.05) between treatments within the same columns are denoted by superscript letters.
PaKa, low protein diet without kombucha; PaKb, low protein diet with kombucha; PbKa, high protein diet without kombucha; PbKb, high protein diet with kombucha.
