Data are expressed as the or median (25th-75th percentile). M-SNCV: median sensory nerve conduction velocity; M-MNCV: median motor nerve conduction velocity; U-SNCV: ulnar sensory nerve conduction velocity; U-MNCV: ulnar motor nerve conduction velocity; S-SNCV: sural sensory nerve conduction velocity; SP-SNCV: superficial peroneal sensory nerve conduction velocity; P-MNCV: peroneal motor nerve conduction velocity; T-MNCV: tibial motor nerve conduction velocity; M-SNAP: median sensory nerve action potential; M-CMAP: median nerve compound muscle action potential; U-SNAP: ulnar sensory nerve action potential; U-CMAP: ulnar nerve compound muscle action potential; S-SNAP: sural sensory nerve action potential; SP-SNAP: superficial peroneal sensory nerve action potential; P-CMAP: peroneal nerve compound muscle action potential; T-CMAP: tibial nerve compound muscle action potential. A value < 0.05 was considered to indicate statistical significance.
