Data are presented as mean ± standard deviation or number of patients (percentage).
*P < 0.05 between patients who did not have vasospasm and patients who did.
&Mann Whitney test was used to compare hs-CRP levels between groups due to that hs-CRP levels were not normally distributed.
Abbreviation: eGFR: estimated glomerular filtration rate; CKD: chronic kidney disease; hs-CRP: high sensitivity-C reactive protein.
Statistical significance based on Student's t-test or chi-square test.
