【摘要】 目的　分析大小骨密度仪不同部位测定结果的相关与回归。方法　对 341名调查对象用两种骨密度仪测量不同部位的骨密度 ,对所获取资料经相关与回归分析。结果　不同部位不同仪器的骨密度值具有很强的相关性 (P <0 0 1) ,以小骨密度仪测量值为自变量 ,以大骨密度测量值为因变量可以建立回归方程。结论　不同仪器测量的骨密度具有很强的相关与回归性。更多还原

【Abstract】 Objective To analysis the correlation and regression of bone mass density(BMD) measured in various sites by two different implements.Methods Three hundred and fourty one subjects’ BMDs in different sites were tested by two implements, and correlation and regression analysis was employed to the data obtained.Results Significant correlation was found between BMDs measured by different implements in various sites( P <0.01); regarding BMDS measured by the small implement as independent variables .BMDs measured by the big one as dependent variables,a regression equation can be set up.Conclusion BMDs measured by different implements had significant correlation and regression.更多还原
