Table 1 Seven ratios that were assessed from the cephalogram

From: Development and validation of a formula for objective assessment of cervical vertebral bone age

Ratio

Parameters assessed

AH/AP

Anterior height/anteroposterior width

PH/AP

Posterior height/anteroposterior width

H/AP

Middle height/anteroposterior width

AH/PH

Anterior height/posterior height

AH/H

Anterior height/middle height

H/PH

Middle height/posterior height

CONC/H

Depth of concavity/middle height

  1. The ratios were named according to the cervical vertebra measured; for instance, AH3/PH3 refers to third cervical vertebra, while AH4/PH4 refers to the fourth vertebra
