EGJ-CI values in relationship to acid exposure and hiatus hernia

	EGJ-CI/SRC	EGJ-CI/CRC

Parameters	mmHg.cm.s	mmHg.cm
Normal controls	205.5 ± 35.6	46.2 ± 7.6
All subjects	167.3 ± 10.7	49.4 ± 2.8
Normal acid exposure (AET < 4.0)	197.2 ± 15.1	56.7 ± 3.6
With type III hiatus hernia	173.6 ± 25.5	50.4 ± 6.4
Without type III hiatus hernia	208.6 ± 18.6	59.7 ± 4.3
Abnormal acid exposure (AET ≥4.0)	134.9 ± 14.5^*	41.4 ± 4.2^**
With type III hiatus hernia	78.1 ± 16.8^***	24.0 ± 4.7^***
Without type III hiatus hernia	194.2 ± 20.4	59.6 ± 5.8

P = 0.003 and

^**

P = 0.006 compared to cohort with normal acid exposure (AET < 4.0).

^***

P < 0.05 compared cohorts with normal acid exposure (AET < 4.0) with hiatus hernia. CRC, corrected for respiratory cycle; EGJ-CI, esophagogastric junction contractile integral; SRC, single respiratory cycle.
