#Values at hospital admission.
bP-value was calculated using the Mann-Whitney U test.
cP-value was calculated using Fisher’s exact/chi-squared test.
*Indicates a significant statistical difference as P<0.05. RBC, red blood cells; HGB, hemoglobin; T1W, T1-weighted; T2W, T2-weighted; SD, Standard deviation
