Values are means ± SD and range in seconds; n= sample size. Shown are suck cycle and suck-swallow cycle duration by treatment (control, palatal anesthesia, palatal saline), by group, for group A by treatment, and for group B by treatment.

^a,b,c,d,e,fGroups with different letters next to the means ± SD are statistically significantly different from each other (P < 0.05). Significant differences across categories are not shown.
