Determination of Significance for Presence and Absence of EGR as Function of Patient Age, Sex, MBq (mCi) of Injected Activity, and GBEF
| Characteristic | Reflux present (n = 38) | Reflux absent (n = 157) | Significance |
| Average age (y) | 51.3 | 50.2 | P = 0.724 |
| Sex | 26% of females | 74% of females | χ2 = 0.707, P = 0.401 |
| 20% of males | 80% of males | ||
| MBq (mCi) injected activity | 192.77 (5.21) | 193.88 (5.24) | P = 0.788 |
| GBEF (n = 117) | 48.8% (n = 43) | 48.7% (n = 74) | P = 0.996 |
