Heart rate variability measurement (a) total power (b) low-frequency (LF) power (c) high-frequency (HF) power (d) LF/HF ratio. Data are mean with error bars showing SD. T0, 10 min before spinal anaesthesia; T1, 10 min; T2, 20 min; T3, 30 min after spinal anaeshthesia; normal group N (●),controlled DM group (□), uncontrolled DM group (○). *P < 0.05 compared to T0; †P < 0.05 compared to normal group; ‡P < 0.05 compared to controlled DM group
