Receiver operating curve for a) age; b) WFNS; c) Fisher grade; d) MFI-11; e) MFI-5; f) NSQIP score; g) temporalis thickness; h) zygoma thickness. Area under curve (95% CI) of age: 0.76 (0.60 – 0.91); WFNS grade: 0.76 (0.62 – 0.91); Fisher grade: 0.72 (0.54 – 0.89); MFI-11: 0.58 (0.40 – 0.77); MFI-5: 0.56 (0.37 – 0.74); NSQIP score: 0.70 (0.54 – 0.86); TMT: 0.82 (0.70 – 0.94); ZGM: 0.62 (0.44 – 0.82) respectively. WFNS: World Federation of Neurological Surgeons: MFI: modified frailty index; NSQIP: National Surgical Quality Improvement Program; TMT: temporalis muscle thickness
