Residual gastric volume after 3 h of the ingestion of an oral supplement containing carbohydrates alone or associated with whey protein: a randomized crossover pilot study

Table 2 Distribution of the GVR during the three phases of the study in the two groups

Phase and group	Mean	SD	Median	Lower	Higher
Fast (phase 1)
CHO	25.3	15.7	18.8	11.8	45.2
WP + CHO	28.2	24.0	19.2	8.4	70.7
After ingestion (phase 2)
CHO	204.0*	12.2	204.7	190.7	220.3
WP + CHO	206.4*	23.5	205.6	168.3	239.5
3 h after ingestion
CHO	23.5	13.6	19.6	11.0	42.2
WP + CHO	25.7	9.3	23.9	13.9	42.1

All between-group comparisons were NS (p > 0.05) in each phase. *p < 0.01 vs phase 1 and phase 2 in each group (within-group comparisons). Repeated-measures ANOVA
CHO Carbohydrate, WP Whey protein, SD Standard deviation
