Multiple regression analysis to detect variables associated with muscle cramps.

amale recipients only. Shown is the Spearman correlation coefficient. Dependent variable: presence of muscle cramps. Bold values depict statistically significant correlations. CMAP = compound muscle action potential, DML = distal motor latency, HFA = high frequency attenuation, LE = lower extremity, MRC = Medical research council, MUAP = motor unit action potential, NCV = nerve conduction velocity, SNAP = sensory nerve action potential.
