Table 2. CORRELATION BETWEEN CH₄ PRODUCTION, STOOL CHARACTERICTICS & COLONIC TRANSIT.

The correlation between stool consistency, stool frequency, colonic transit and methane production is shown for methane producing constipated subjects. Adjusted correlation coefficients (R²) are shown.

	Baseline CH₄	Peak CH₄	AUC CH₄
Stool consistency	R² = 0.01	R² =0.07	R² =0.01
Stool frequency	R² =0.03	R² =0.02	R² =0.02
Colonic transit	R² =0.52^*	R² =0.54^*	R² =0.56^*
