Results of receiver operating characteristic curve analysis. Triangle: pressure, asterisk: strain, black square: pressure-strain ratio, black circle: distal latency of motor nerve study, distal latency of sensory nerve conduction study, white square: cross sectional area of median nerve. The areas under the curves were 0.688, 0.788, 0.771, 0.650, 0.727, and 0.535 for the pressure, strain, pressure-strain ratio, motor latency, sensory latency, and area, respectively
