Table 2. Primary outcome.

Changes in total gastric volume after ingesting a nutrient liquid meal (400 mL, 200 kcal) between the DA-9701 (n = 18) and the placebo group (n = 19).

Variables	DA-9701 group (n = 18)	Placebo group (n = 19)	a Mean difference (95% CI)	P-value
TGV, mL (mean ± SD)
Pre-test meal	139.2 ± 41.1	151.9 ± 43.4
15 min after test meal	486.7 ± 55.9	521.6 ± 45.7
Change	347.5 ± 44.7	369.7 ± 40.9
b Adjusted TGV at 15 min, mL (LSM ± SE)	491.3 ± 9.9	517.2 ± 9.6	−25.9 (−54.0 to 2.3)	0.070

CI, confidence interval; TGV, total gastric volume; LSM, least squares mean

^a Difference in TGV between the DA-9701 and the placebo group 15 min after the test meal

^b Estimated from analysis of covariance adjusted for value of TGV at the pre-test meal after normality checking (P > 0.05)
