Fig. 2From: In vivo experimental validation of detection of gastric slow waves using a flexible multichannel electrogastrography sensor linear arraySummary of cutaneous EGG correlation with serosal recordings. A Correlations between frequencies (R2 = 0.641) and amplitudes (R2 = 0.011). B Comparison of cutaneous EGG characteristics (frequency, amplitude, and phase-shift) between normal and abnormal slow waves based on serosal recording classificationsBack to article page
