Table 3. Frequency of diagnosis of GERD by different methods in children with / without esophageal symptoms

Methods	Group A (with esophageal symptoms) n = 63	Group B (no esophageal symptoms) n = 62	Total n = 125	p-value
Methods	n / Total (%)	n / Total (%)	n / Total (%)	p-value
EGDS	32/43 (74)	27/39 (69)	59/82 (72)	0,6036^*
Fluoroscopy	48/54 (89)	39/53 (74)	87/107 (81,3)	0,042^*
24-pH	4/9 (44)	1/11 (9)	5/20 (25)	0,127^**
pH-MII	24/26 (92)	16/17 (94)	40/43 (93)	1^**
Total	58/63 (92)	50/ 62 (81)	108/125 (86,4)	0,0637^*
