Comparison of values of H₂S, CH₃SH and CH₃SCH₃ among the three types of interventions.

Type of intervention	H2S		CH3SH		CH3SCH3
	Median (IQR)	P	Median (IQR)	P	Median (IQR)	P
AO	192 (321)2	<0.0001∗	24 (62)2	0.009∗	13 (42)	0.105
CHX-CPC-Zn	32 (59)1		7 (21)1		5 (16)
Saline	136 (217)2		26 (63)2		10 (23)

AO = antioxidant; IQR = interquartile range.

Values represent Median (IQR) in parts per billion.

P value for the statistical comparison using Kruskal–Wallis test; ∗statistically significant.

¹Significantly lower than AO and saline (p < 0.001); ²No significant difference between saline and AO (p > 0.05).
