WAG concentrations measured at the level of the opening of the (A) 500-ml jar and (B) 1000-ml jar. Data analysis using 2-factor ANOVA showed that time was the only significant (P < 0.0001) factor affecting WAG concentration when the 500-ml jar was used; neither time nor liquid volume significantly effected WAG concentration during use of the 1000-ml jar. There is, however, a clear trend toward higher WAG concentrations with greater time and liquid volume in all cases. A Student t test showed that using the 500-ml jar generated WAG concentrations that were significantly (P < 0.05) greater than those from the 1000-ml jar at all time points and liquid volumes except 0.1 ml for 3 min (P = 0.057). Bars represent SEM.
