Figure 3From: Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressureIntra-class correlation coefficients (ICC) and coefficient of variation (CV) obtained by one observer. Intra-class correlation coefficients (ICC) and coefficient of variation (CV) of cervical resistivity values obtained by a repeat measurement by one observer applying soft (0.8 Newton) and firm (2.2 Newton) force on the cervix for each of the 2 probes studied.Back to article page
