Table 4 Positive likelihood ratios for the combined dental maturation stages for the diagnosis of growth phases

From: Diagnostic performance of combined canine and second molar maturity for identification of growth phase

Tooth and maturation stage	Growth phase positive
Tooth and maturation stage	Pre-pubertal	Pubertal	Post-pubertal
Combination of two stages
Canine G with second molar F	2.0 (1.0 to 4.1)	1.2 (0.6 to 2.6)	0.2 (0.1 to 0.8)
Canine G with second molar G	0.7 (0.2 to 2.0)	2.6 (0.9 to 8.0)	0.6 (0.1 to 2.5)
Canine H with second molar F	1.0 (0.4 to 2.6)	1.1 (0.4 to 3.4)	0.8 (0.3 to 2.6)
Canine H with second molar G	0.3 (0.2 to 0.4)	2.3 (1.6 to 3.4)	1.8 (1.2 to 2.6)
Combination of three stages
Canine G with second molar F/G	1.5 (0.8 to 2.6)	1.5 (0.9 to 2.8)	0.3 (0.1 to 0.7)
Canine H with second molar F/G	0.4 (0.2 to 0.5)	2.1 (1.5 to 2.9)	1.5 (1.1 to 2.2)
Canine G/H with second molar F	1.4 (0.8 to 2.5)	1.5 (0.8 to 2.6)	0.3 (0.1 to 0.8)
Canine G/H with second molar G	0.4 (0.2 to 0.5)	2.1 (1.5 to 3.0)	1.5 (1.0 to 2.2)

Data are presented as mean (95% confidence interval). The cases for the canine stages up to stage F or the second molar stages up to stage E, and those for the second molar stages from stage H, which showed positive LHRs ≥10 for the diagnosis of the pre-pubertal and post-pubertal growth phases, respectively, are not shown.
