^aData with a normal distribution are presented as mean (standard deviation), while the skewed data were expressed as the median (quartile range)
^bValues in boldface were major factor loadings that contribute to identify Factor 1
^cValues in boldface were major factor loadings that contribute to identify Factor 2
