aDistal baseline impedance from high-resolution impedance manometry (DBI-HRIM) represents the baseline impedance from high-resolution impedance manometry (BI-HRIM) obtained from the most distal esophageal impedance sensor using the Medtronic HRIM catheter.
bDistal mean nocturnal baseline impedance (MNBI) represents the averaged MNBI values for 3,5,7, and 9 cm above the lower esophageal sphincter (LES).
