CALCA and aneurysm: After having detected significant correlations between increased AUC CGRP levels and various hrQoL domains in the univariate analysis, we developed a multivariate model including AUC CGRP, age, gender, treatment modality (MS vs. EV vs. pSAH), site of the aneurysm, HH grade, WFNS grade, Fisher grade, initial GCS, and CV to analyze their impact on the respective hrQoL domains.
