Variable		Amount (mm)	P	Rate (mm/mon)	P
Sex			0.357		0.987
	Female (n=24)	0.78±0.20		0.11±0.07

CEJ-to-ABC distance			0.828		0.664
	<2 mm (n=26)	0.94±0.33		0.12±0.08
	≥2 mm (n=25)	0.88±0.46		0.17±0.11

Data are shown as mean±standard deviation. Statistical significance was determined using the Mann-Whitney U test.

CEJ: cementoenamel junction, ABC: alveolar bone crest.
