Crude and adjusted local odds ratios (OR, scale at right) for NHL at a residential lag time of 20 years in Iowa. Clusters of statistically significant elevated odds ratios are identified with a solid white line and clusters of statistically significant lowered odds ratios are identified with a dashed black line. Crude model: span = 0.625 (p-value = 0.21); Adjusted model: span = 0.625 (p-value = 0.14). Model adjusted for age, gender, race, education, and home termite treatment before 1988.
