3. Figure 2
Independent predictors of symptom improvement after management of reflux disease. (A) Prediction of linear change is shown as risk ratios and 95% confidence intervals, values not crossing the zero axis are significant. *P = .027 for DSI and P = .002 for GSS; **P = .026 for GSS. (B) Prediction of 50% or more improvement is shown as odds ratios and 95% confidence intervals, values not crossing the value of 1 are significant. *P = .014, **P = .05. In both instances, abnormal AET independently predicted symptom response after antireflux therapy; impedance-SAP complemented prediction, especially when GSS was used as the outcome measure.
