AST, aspartate aminotransferase; ALT, alanine aminotransferase; BMI, body mass index; γ-GTP, gamma-glutamyl transpeptidase.
Data are mean values (standard deviation) or percentage values for categorical variables, unless otherwise noted.
a
Reported as median (interquartile range).
b
p Value for comparing the changes in evacuees to the changes in non-evacuees between before and after the earthquake.
