Breakdown of reflux event tally based on whether events were short (one or two data points for the catheter system or only one for the bravo system) or long
| Slimline catheter | Bravo | |||
|---|---|---|---|---|
| Short events | Long events | Short events | Long events | |
| *p<0.05, catheter versus Bravo similar reflux event duration; †p<0.05, short versus long within pH system (catheter or Bravo). | ||||
| No of events/24 h (mean (SD)) | 45.5 (25.5)*† | 24.3 (18.6) | 18.5 (9.5) | 19.4 (14.9) |
| Concordance with Bravo (%) | 32.7 | 76.8 | – | – |
| Concordance with catheter (%) | – | – | 49.3 | 93.5 |
| Nadir pH of events (mean (SD)) | 3.1 (0.2)*† | 2.8 (0.4)* | 3.5 (0.3)† | 3.1 (0.3) |
| Total integrated acidity, all subjects (mmol min/l) | 162.1 | 1986.8 | 15.0 | 1430.1 |
