Using the results from Problems 13.68 and 13.69, obtain an estimate of the RR of breast cancer, comparing women who differ by 10 g/day on total fat intake on the DR, assuming age and alcohol intake have no measurement error and are not correlated with total fat intake?

A logistic-regression analysis similar to that presented in Example 13.73 (on page 743) was run relating breast-cancer incidence in 1980–1984 to calorie-adjusted total fat (heretofore referred to as total fat intake) as reported on a 1980 FFQ. In addition, age in 5-year categories and alcohol in categories (0, 0.1–4.9, 5.0–14.9, 15+ g/day) were also controlled for. The regression coefficient for a 10-g/day increase in total fat intake was –0.163 with standard error = 0.135.
