Summary of Bleeding Index over time

Time point	Mean Bleeding Index (±SD)		Between Treatment Comparison*
	0.1% o-cymen-5-ol/ 0.6%ZnCl2 (N = 112)	0.204% Sodium Fluoride (N = 112)	Mean Difference (%)	95% CI	P-value
Pre-Prophy Baseline	0.63 ± 0.250	0.64 ± 0.227
Randomisation	0.20 ± 0.110	0.20 ± 0.101
Week 6	0.29 ± 0.144	0.35 ± 0.141	−0.06 (−18.5%)	(−0.08, −0.04)	<0.0001
Week 12**	0.13 ± 0.075	0.20 ± 0.100	−0.09 (−37.8%)	(−0.11, −0.07)	<0.0001

^*0.1% w/w o-cymen-5-ol/ 0.6%w/w zinc chloride (ZnCl₂) dentifrice vs 0.204%w/w sodium fluoride dentifrice, a negative difference favours the experimental dentifrice. Comparison based on model-adjusted means. Difference based on transformed values (square root transformation).

^**N = 104 and N = 101 were assessed in each group respectively at Week 12.
