Ultrasonographic study of postcibal gastro-esophageal reflux and gastric emptying in infants with recurrent respiratory disease

Figure 1 Number of postcibal gastro-esophageal reflux episodes, as determined by ultrasound, in controls (n = 31) and in infants with recurrent respiratory diseases (n = 35). Horizontal dotted line indicates the mean+2SD in the normal control group. Squares and continuous horizontal lines indicate medians. Differences between the groups were tested by using ANOVA, followed by Fisher’s LSD multiple comparison test. ^aP<0.05 vs controls; ^cP<0.05 vs chronic cough.
