aValues are back transformed from log10 (Geometric mean and 95% CI), from unadjusted models.
bValues are unadjusted M (SD).
cAUC refers to the area under the curve, calculated from individual plots of amount consumed (%) over time (%). Larger AUCs indicate more decelerated drinking. Values of AUC taken from participants for whom all sips were recorded as volumes (n = 16).
dValues are back transformed from log (Geometric mean and 95% CI), from models adjusting only for repeated-measures.
