The Dietary Modification intervention has also yielded new findings, after nearly two decades of follow-up. During the dietary intervention period (median, 8.1 years), it was found that a low-fat dietary pattern led to a lower incidence of death (from all causes) after breast cancer (40 deaths versus 94 in the "normal diet" arm; HR, 0.65; 95% CI, 0.45 to 0.94, P = .02.). After a median 16.1 years of cumulative follow-up (inclusive of the intervention period), further analysis showed that this benefit persisted (234 deaths versus 443 in the "normal diet" arm; HR, 0.82; 95% CI, 0.70 to 0.96 with P = .01). A more recent update, with 19.6 years of cumulative follow-up, reported the persistent reduction of death (from all-causes) after breast cancer continued (359 v 652 deaths; HR, 0.85; 95% CI, 0.74 to 0.96; P = .01) and a statistically significant reduction in deaths as a result of breast cancer (breast cancer followed by death directly attributed to the breast cancer) emerged (132 v 251 deaths; HR, 0.79; 95% CI, 0.64 to 0.97; P = .02).
