Length-of-stay (LOS) among three preterm groups (HI-healthy infants, RDS-respiratory distress syndrome, and CLD-chronic lung disease). Groups were randomized to either SHAM or PULSED pacifier treatments. A significant group by treatment interaction effect was present (p<.001), and Bonferroni pairwise comparisons for RDS (** p<.01, d=.47) and CLD infants (*** p<.05, d=.39). Error bars depict standard deviation.
