Table 1. Predictor information and inclusion.

The cancers that each predictor was included for are denoted by ‘l’ (lung), ‘b’ (breast), ‘c’ (colorectal), ‘p’ (prostate), ‘all’ (all 4 cancers), and ‘env’ (as an elevation replacement in the environmental analysis). The data collection period, number of counties with non-missing values after quality control, and unweighted mean and standard deviation are also reported.
