Stature estimation from sternum length using computed tomography-volume rendering technique images of western Chinese.
The objective of the present investigation was to generate linear regression models for stature estimation on the basis of sternum length derived from computed tomography-volume rendering technique (CT-VRT) images for Western Chinese. The study sample comprised 288 individuals of Western Chinese, including 124 females and 164 males, with documented ages between 19 and 78 years, and was randomly divided into two subgroups. The linear regression analysis for the calibration sample data yielded the following formulae: male stature (cm) = 137.28 + 1.99*combined length of manubrium and mesosternum and female stature (cm) = 111.59 + 3.51* combined length of manubrium and mesosternum. Pearson's correlation coefficients for the regression models were r = 0.459 and r = 0.541 for the male and female formulae, respectively. The standard errors of the estimate (SEE) were 4.76 cm for the male equation and 6.73 cm for the female equation. The 95% confidence intervals of the predicted values encompassed the correct stature of all specimen in the validation sample. The regression equations derived from the sternum length in the present study can be used for stature estimation and the length of the sternum is a reliable predictor of stature in Chinese when better predictors of stature like the long bones are not available, and the CT-VRT method may be a practical method for stature estimation.
