Comparison of day-to-night change (dipping) rates based on the “10%” rule
| Dipping | Magnitude of dipping | Enuretic patients, n (%) | Healthy controls, n (%) | Significance according to chi-square test |
|---|---|---|---|---|

| <10% | 37 (82.2) | 13 (59.1) | p = 0.041* | |
| Diastolic dipping | >10% | 24 (53.3) | 18 (81.8) | χ2:5.12* |
| <10% | 21 (46.7) | 4 (18.2) | p = 0.017* | |
| Mean dipping | >10% | 13 (28.9) | 11 (50.0) | χ2:2.86 |
