Antibacterial effect and impact on caries activity of nanosilver fluoride and silver diamine fluoride in dentin caries of primary teeth: a randomized controlled clinical trial

Table 4 Multilevel binary logistic regression assessing the effect of NSF compared to SDF on reduction in S. mutans counts, reduction in lactobacilli counts, and change in lesion activity

	Reduction versus no reduction in S. mutans counts	Reduction versus no reduction in lactobacilli counts	Non active versus active lesions
AOR	1.281	1.888	1.355
95% CI	0.300, 5.475	0.506, 7.044	0.235, 7.803
P value	0.737	0.341	0.731
-2LL	611.537	591.885	630.235
% Correctly classified	88.5%	86.9%	90.8%
Model P value	0.669	0.868	0.719

Models are adjusted for age, gender, mother education, tooth type, brushing frequency, dental visits frequency, and sugar consumption. The model for lesion activity is additionally adjusted for the reduction in S. mutans and lactobacilli in lesions. -2LL: Log likelihood
