Extraesophageal Reflux: What Is the Best Parameter for pH-Monitoring Data Analysis from the Perspective of Patient Response to Proton Pump Inhibitors?

Table 2

Number (N) and percentage (%) of patients diagnosed with EER (EER⁺) and without EER (EER⁻) using three different parameters of pH monitoring analysis (NOR: number of refluxes, AET: acid exposure time, and RAI: reflux area index).

Parameter	EER^+ (N)	EER^+ (%)	EER^− (N)	EER^− (%)
NOR	29	35,80	52	64,20
AET	23	28,40	58	71,60
RAI	21	24,93	60	75,07
