The following blood sampling data were not measured: albumin level in one case in the acute esophageal mucosal lesion (AEML) group (1 in the non-black esophagus); glucose level in six cases in the AEML group (one and five cases of the black and non-black esophagus, respectively) and three cases in the reflux esophagitis Los Angeles classification grade D (RE-D) group; C-reactive protein level in one case in the AEML group (1 in the non-black esophagus); and lactate level in 23 cases in the AEML group (5 and 18 cases of the black and non-black esophagus, respectively) and 15 cases in the RE-D group. BUN: Blood urea nitrogen; IQR: Interquartile range; SD: Standard deviation.
