Table 9 Linear regression between butyric acid (x, μmol/g) and serotonin in different tissues¹

Items	b₀	b₁	R²	P-value
Serotonin
Serum, ng/mL	24.705	67.739	0.624	< 0.001
Follicular fluid, pg/mL	−118.494	20.362	0.697	< 0.001
Colon, ng/mg	1.266	0.181	0.281	0.008

¹The linear regression model is y = b₀ + b₁ × x, where b₀ denotes serum serotonin concentrations when the butyrate concentration in colonic content was 0 μmol/g, and b₁ denotes the serotonin increment when the colonic butyrate content was increased to 1 μmol/g
