Abstract:
Objective To establish regression m odel betw een craniofacial lines and body height by m ea-suring craniofacial lines in Southw est H an m ales using C Tand to accum ulate data for the study of foren-sic anthropology. Methods H ead C Tdata of 273 H an m ales in Southw est w ere collected and 7 cranio-facial lines w ere determ ined. M ultiplanar reconstruction and volum e rendering w ere perform ed by im age post-processing softw are and the selected lines w ere m easured. The relationship betw een each m easuring indicator and body height w as analyzed using SPSS 21.0 softw are. The regression equation of body height estim ation w as established and 50 sam ples w ere selected again and put into the m athem atics m odels to verify its accuracy. Results The linear regression equations of 7 lines w ere established (P<0.05). The correlation coefficients of the unary linear regression equations w ere 0.190-0.439 and the standard errors of the estim ate (SEE) w ere 4.597-5.023 cm . The correlation coefficients of the m ultiple linear regression equation w ere 0.494-0.524 and the SEEw ere 4.418-4.458 cm . The return tests show ed that the highest ±1SEEaccuracy of the m ultiple regression equation:y=83.959+3.589 x6+2.573 x2, w ere 30%;and the highest ±2SEEaccuracy of the m ultiple regression equation: y=72.646+3.316 x6+1.586 x2+1.553 x4+2.211 x3, w ere 92% . Conclusion There is significant linear correlation betw een 7 selected lines and the stature in this study, and the plural linear regression equation established could be applied for estim ating the stature of Southw est H an m ales.
