Individual before and after cisapride RIs (percentage of time pH: <4.0). Cisapride treatment in symptomatic infants as a group significantly reduced the RI; however, 8 infants (bold lines) showed no decrease in RI after a week on cisapride therapy.
Individual before and after cisapride RAAP indexes. An increase was seen in 5 of the infants. One infant (bold line) had an unusually large increase. If the data from this outliner infant were to be excluded, the effect of cisapride on RAAP would be significant (P = .034).
