Analysis of people with different states of anxiety based on 24-h pH monitoring results (rank mean, N = 518).
| Variables | No anxiety (0–7points, N = 266) | Mild anxiety (8–10points, N = 89) | Moderate to severe anxiety (11–21 points, N = 163) | P |
|---|---|---|---|---|
| Number of refluxes (pH < 4) | 206.79 | 271.80 | 338.81 | < 0.001 |
| % Time spent in reflux | 205.03 | 276.23 | 339.25 | < 0.001 |
| Number of long refluxes (T ≥ 5 min) | 214.19 | 289.90 | 316.90 | < 0.001 |
| DeMeester score | 205.02 | 269.39 | 343.01 | < 0.001 |
| Oesophageal acid exposure | < 0.001 | |||
| Physiological reflux | 210 (78.95%) | 47 (52.81%) | 42 (25.77%) | |
| Pathological reflux | 56 (21.05%) | 42 (47.19%) | 121 (74.23%) | |
| Diagnostic subgroup | ||||
| Physiologic reflux | 204 (76.69%) | 44 (49.44%) | 27 (16.56%) | < 0.001 |
| NERD | 35 (13.16%) | 29 (32.58%) | 94 (57.67%) | |
| RE | 27 (10.15%) | 16 (17.98%) | 42 (25.77%) | |
The results of the Kruskal–Wallis test are expressed as rank averages; NERD non-erosive reflux disease, RE reflux esophagitis.
