Comparisons between groups were not completed because the laboratory item was grade variables.

Data are presented as n/n (%) or mean ± SD or median (interquartile range). The level of each laboratory finding was divided as normal and abnormal levels (lower than normal or higher than normal) according to the standard normal physiological range of our research centers. Average levels of each group were described by mean ± SD or median (interquartile range). Numbers and proportions of patients with different levels of each laboratory item were presented above.
