**Table 2.** Comparison of CMAP, SNAP and NCV of Tibial and Sural Nerves in Cases and Controls
	Motor CMAP (µV)		Motor NCV (m/s)		Sensory SNAP (µV)		Sensory NCV (m/s)
	Control	Case	Control	Case	Control	Case	Control	Case
The CMAP and NCV of right tibial nerve were significantly reduced in the cases as compared to controls which were found out to be statistically significant, suggesting that cases had motor axonal neuropathy. CMAP: compound muscle action potential; NCV: nerve conduction velocity; SNAP: sensory nerve action potential.
