-
c P < 0.05.
-
d Estimate of the regression coefficient of the relationships between log-transformed for blood cadmium and lead levels and log-transformed for age-adjusted mortality rates from all-cancer and stomach cancer using multiple linear regression and estimate of the regression coefficient of the relationships between log-transformed for blood cadmium, lead and zinc levels and the original age-adjusted mortality rates from all-cancer and stomach cancer using ridge regression.

e A tolerance <0.10 indicates that collinearity must be considered.
-
f Variance inflation factor; If >10, collinearity must be considered.
