Comparison of superoxide concentrations at kidney meridians KI 1 and governing vessel GV 16.

	Control Group (n = 7)	Grounding Group (n = 8)	p
Kidney Meridians KI 1 electrochemical signals
Baseline	50.18 ± 58.13	30.11 ± 10.85	0.755
12 weeks	−76.17 ± 383.03	−173.96 ± 522.06	0.755
Governing Vessel GV 16 electrochemical signals
Baseline	27.45 ± 85.98	15.80 ± 32.67	0.228
12 weeks	−37.17 ± 230.56	−113.58 ± 294.76	0.414

Values are expressed as the mean ± standard deviation. The Mann–Whitney U test was used to analyze the differences between groups (×10⁻¹⁵ mole).
