【摘要】Objective To provide a scientific reference value of activated partial thromboplastin time ( APTT) for the healthy old people in China.Methods 10 053 examples healthy subjects'APTT were collected from 72 hospitals in cities,counties and research institu-tes.The relationship between the reference value of APTT and 7 geographical factors was studied by using the method of correlation analysis. The method of Stepwise regression and curve estimation analysis were used to infer regression equations between APTT and the geographical factors,the best regression equation then was chose.Then,the Kriging interpolation was used to explore spatial distribution of APTT using Arcgis10.0.Results There was very significant relationship between APTT of healthy old people and altitude with correlation analysis.As the altitude increased gradually,the APTT of healthy old people gradually increased correspondingly.The best regression equation between APTT and altitude was that y=30.78+0.002 999X1±0.451.The distribution of APTT of Chinese healthy old people gradually increased from east to west,which was seemingly ladder-shaped.Conclusions The distribution
