Methods and Results: We colleted the lung compliance data from 4489 (2726 males, 1763 females) healthy adult Chinese from 46 cities and counties across China. The relationship between lung compliance data and geographic factors (altitude [X1], annual sunshine duration [X2], annual mean air temperature [X3], annual mean relative humidity [X4], and annual precipitation [X5]) were assessed by correlative analysis and co-linearity diagnostics. Then we analyzed the relationship between the reference value and the geographical factors by using the method Principal Component Analysis.
