Table I.

Bacterial counts (colony-forming units (CFUs)/swab) on day 4 before and after irrigation and treatment with stabilized hypochlorous acid (HOCl) and the control (sterile saline (0.9% NaCl))

	HOCI (n = 19)	NaCI (n = 19)	p-value
Before treatment, median (IQR)	70 (0–3,300)	11,500 (20–52,000)	0.015
After treatment, median (IQR)	0(0–390)	1,100 (10–30,000)	0.0023
p-value	0.023	0.0044

IQR: interquartile range; CFUs: colony-forming units (derived from 5% blood agar plates. No swarming from Gram-negative species such as Proteus sp. was detected; thus, counting the blue plates was unnecessary).
