Leptin (ng/mL) in female and male patients at different time intervals, 0–240 h after subarachnoid haemorrhage (SAH) F female patients (white bars), M male patients (grey bars). *Significant difference p < 0.05. Leptin values at admission, 0–48 h, after SAH and thereafter distributed into 48 h intervals: 49–96, 97–144, 145–192, 193–240 h after SAH. Male patients: 0–48 h: n = 17, 49–96 h: n = 17, 97–144 h: n = 16, 145–192 h: n = 16, 193–240 h: n = 16. Female patients: 0–48 h: n = 37, 49–96 h: n = 37, 97–144 h: n = 35, 145–192 h: n = 34, 193–240 h: n = 34. Dotted lines normal values for males: 4.3 ± 0.7 ng/mL/females: 13.0 ± 2.3 ng/mL
