Basic characteristics of the study population.

	Total	Group HP	Group AgP
Sample size	505	133	372	—
Age^a				0.058
Male/female	205/300	53/80	152/220	0.839
PD (mm)^a	4.06 ± 1.65	1.76 ± 0.46	4.85 ± 1.06	<0.01
AL (mm)^a	3.32 ± 0.11	0	4.45 ± 1.52	<0.01

AgP: aggressive periodontitis; HP: healthy participant; DBP: vitamin D-binding protein; PD: probing depth; AL: clinical attachment loss. Data were presented as mean ± SD. by Student’s -test for continuous variable and by Pearson’s chi-square test for categorical variable.
