Table 3. Impedance differences between contacts.

Contact Usagea Mean impedance (Ω)b
0 44% 1347*
1 49% 1265†
2 51% 1230†
3 29% 1309*
a

Usage refers to the relative frequency of a contact being active; this likelihood varied significantly between contacts (P < .001).

b

Impedances with the same symbol (* or †) differed with P < .05 while impedances with different symbols differed with P < .001.
