From: Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressure

Figure 5

Variability of cervical resistivity by application pressure for each probe studied by Observer 1. a: Mean (SE) cervical resistivity values across 14 measured frequencies using the 3 mm probe by force of probe application to the cervix. b: Mean (SE) cervical resistivity values across 14 measured frequencies using the 12 mm probe by force of probe application to the cervix.
