Gastroesophageal reflux disease in pediatric esophageal atresia: Assessment of clinical symptoms and pH-impedance data

Figure 4 Kruskal-Wallis test (P < 0. 001) with post hoc analysis (Dunn’s test) of mean nocturnal baseline impedance data in the study groups. Study groups are: (1) NERD; (2) RE; (3) EA with GERD; (4) EA without GERD. ^aP < 0.05. nr: MedCalc numbers the factors. In the output you see a list of factors, with factor label, n and average rank. The factor label is preceded with a number between brackets. The "nr" in "Different (P < 0.05) from factor nr" refers to that number. NERD: Nonerosive reflux disease; RE: Reflux esophagitis; EA: Esophageal atresia; GERD: Gastroesophageal reflux disease.
