Key result
A novel dry electrode yielded an ECG signal-to-noise ratio comparable to a standard gel electrode (17.29 vs 16.33; P=0.2573) without requiring skin preparation.

Absolute Event Rate: 17.29% vs 16.33%
p-value: p=0.2573
A novel dry electrode provided comparable ECG signal quality to a standard gel electrode without the need for skin preparation or electrolytic solution.
Rood et al. (2006) conducted an RCT in Healthy subjects (n=11). Novel dry electrode vs. Standard gel electrode (3M Red dot) was evaluated on Signal to noise ratio (p=0.2573). A novel dry electrode yielded an ECG signal-to-noise ratio comparable to a standard gel electrode (17.29 vs 16.33; P=0.2573) without requiring skin preparation.
