|
Association of Change in Patient's GSR From Beginning to End of Study Visit With GERD Symptom Severity 2 Weeks Later
Lasso di tempo: Beginning to end of study visit (1 hour or less for change in GSR)
|
Galvanic skin response (GSR) was measured with a device from ADInstruments during the baseline study visit.
Values ranged from 0.93 - 12 micro-Siemens (μS).
Change in GSR was calculated as mean value of GSR for the first 2 minutes of the study visit minus mean value of GSR for the last 2 minutes of the study visit.

Beginning to end of study visit (1 hour or less for change in GSR)

|
Association of Change in Patient's High Frequency HRV From Beginning to End of Study Visit With GERD Symptom Severity 2 Weeks Later
Lasso di tempo: Beginning to end of study visit (1 hour or less for change in HRV/RMSSD)
|
Heart rate variability (HRV) was measured using a device from ADInstruments gathering data at 256 Hz.
We used the RMSSD (Root Mean Square of the Successive Differences) value as a proxy for high frequency HRV.
Measured values ranged from 0 - 150 msec.
Change in high frequency HRV was calculated as the RMSSD value for the first 5 minutes of the study visit minus the RMSSD value for the last 5 minutes of the study visit.

Beginning to end of study visit (1 hour or less for change in HRV/RMSSD)

Correlation Between Concordance in GSR Between Patient and Physician During the Study Visit and Percent Change in Patients' GERD Symptoms Over 2 Weeks
Lasso di tempo: Beginning to end of study visit (1 hour or less for concordance between patient and physician GSR)
|
Concordance in galvanic skin response (GSR) between patient and physician was calculated using an established approach (Marci CD, 2007; PMID 17299296) to create a single index value for the visit.
The natural logarithm of this value was taken to reduce skew.
A value greater than 0 means more than 50% concordance in the data, a value less than zero means less than 50% concordance in the data.

Post GERD Symptom Severity
Lasso di tempo: 2 weeks (baseline and 2 week follow-up)
|
GERD symptom severity at follow-up was assessed by self-report on a 7-day symptom diary (symptoms collected days 8-14 after the study visit).
Possible daily scores ranged from 0-12 with higher scores indicating more severe symptoms (sum of daytime heartburn, nighttime heartburn, and acid regurgitation symptoms each rated 0-4 in severity [none, mild, moderate, severe, very severe]).
Daily scores across the 7 days were averaged to create the Post GERD symptom severity score.

Percent Change in Patient's GERD Symptoms
Lasso di tempo: 2 weeks (baseline and 2 week follow-up)
|
Percent change in patient's GERD symptoms was calculated as: (post GERD symptom severity - baseline GERD symptom severity) / baseline GERD symptom severity*100. GERD symptom severity scores were averaged across 7 day baseline and follow-up periods from a symptom diary (adapted from Miner P, 2002; PMID 12094846). Scores ranged from 0-12 with higher scores indicating more severe symptoms (sum of daytime heartburn, nighttime heartburn, and acid regurgitation each rated 0-4 in severity [none, mild, moderate, severe, very severe]). |
