Regression model results for brain cancer incidence and research reactor number. Multivariate regression model results that include predictor variables, beta (β) coefficients, t-values, and p-values. Results were significant only for research reactors alone, so a simple linear regression model followed each significant result for use in graph creation. Significant results are given in bold
