Analysis of people with different states of anxiety based on 24-h pH monitoring results ($\overline{\text{x}}$ ± s, N = 518).

Variables	No anxiety (0–7points, N = 266)	Mild anxiety (8–10 points, N = 89)	Moderate to severe anxiety (11–21 points, N = 163)	P
Number of refluxes (pH < 4)	55.26 ± 64.35	88.82 ± 99.00	117.03 ± 118.79	< 0.001
% Time spent in reflux	3.47 ± 6.81	6.46 ± 8.90	8.29 ± 9.76	< 0.001
Number of long refluxes (T ≥ 5 min)	1.58 ± 3.63	3.17 ± 4.44	3.50 ± 4.36	< 0.001
DeMeester score	14.51 ± 24.86	25.08 ± 33.68	33.10 ± 36.44	< 0.001
