Abbreviations: HCs, healthy controls; HGG, high-grade glioma; IDH, isocitrate dehydrogenase; LGG, low-grade glioma; WHO, World Health Organization.
Sociodemographic characteristics are presented for HCs. For glioma patients, sociodemographic and clinical patient characteristics are presented. Additionally, sociodemographic and clinical characteristics are presented for LGG and HGG patients separately, as these groups are compared in post hoc analyses. Values are indicated as number of participants (%) unless indicated otherwise.
