Relationships of influencing factors with Chinese Han students’ FVC in 2019 using GAM. FVC forced vital capacity, GAM generalized additive model, PM2.5 particulate matter with aerodynamics diameter < 2.5 μm. A Effect of age on FVC in the multivariable GAM; B Effect of height on FVC in the multivariable GAM; C Effect of GDP per capita on FVC in the multivariable GAM; D Effect of urbanization rate on FVC in the multivariable GAM; E Effect of longitude on FVC in the multivariable GAM; F Effect of latitude on FVC in the multivariable GAM; G Effect of PM2.5 on FVC in the multivariable GAM; H Effect of park green space on FVC in the multivariable GAM. The values of PM2.5 in the table represented the annual mean PM2.5 value in 2019; GAM model was adjusted for sex and area; adjusted R-Squared for this model was 0.937 and deviance explained was 93.7%
