*All temporal models are piecewise loglinear adjusted for race, fire department and birth cohort.
†p Value of LRT comparing the base model to the model with two or more exposure windows.
AE, age at exposure; EP, exposure period; LRT, likelihood ratio test; MN, malignant neoplasm; TSE, time since exposure.
