Diagnostic evaluation of the cervical vertebral maturation stages combined for the identification of the zygomaticotemporal suture maturation stages

Indicators for diagnostic evaluation	CS1 and CS2 (variable diagnosed: ZTS stage B)	CS1–CS3 (variable diagnosed: ZTS stage B and C)	CS6 (variable diagnosed: ZTS stage D and E)
Sensitivity (%)	73.4	59.3	42.1
Specificity (%)	92.9	100.0	98.0
PPV (%)	77.0	100.0	85.7
Positive LR	10.33	Infinity	21.47

CS, cervical stage; ZTS, zygomaticotemporal suture; PPV, positive predictive value; LR, likelihood ratio.
