Average reflux finding score (RFS) and its standard deviation (SD) in group of patients with extraesophageal reflux confirmed by pH monitoring (EER+) and group of patients without EER (EER−) using three different parameters (NOR: number of refluxes, AET: acid exposure time, and RAI: reflux area index). The two-sample Student’s t-test was for statistical analysis of differences between the EER+ and the EER− group.
|NOR||8.00 ± 3.10||6.31 ± 2.67||0.0166|
|AET||7.93 ± 2.65||6.15 ± 2.83||0.0071|
|RAI||8.57 ± 3.00||6.16 ± 2.59||0.0007|
