Context Evidence is lacking that a dietary pattern high in vegetables, fruit, and fiber and low in total fat can influence breast cancer recurrence or survival.
長いんで、短く Evidence is lacking that diet can influence breast cancer outcome.
じゃあCanの代わりに現在形Do/doesを使ったとします。 The evidence is lacking that diet influences breast cancer. 「食べ物が乳癌に影響を与えている証拠は足りない。」と簡単に訳せるんだけど、私の偏見ですが、ここでは、世間で、もう既に「食べ物が乳癌に影響を与えている」と信じきっていると提言していることになります。
CANやDo/doesの代わりにWillを使ってみると
Evidence is lacking that diet will influence breast cancer outcomes.
There are a good news and a bad news about medical school education. The good thing is that 50%(half) of what you learn in medical school will prevail to be correct in the future. The bad news is that we don't know which half. (医大で学ぶことではいい事と悪いこと2種類ある。いい事は、学んでいることの50%が将来正しいと認められる。悪い事はそのどの50%が正しいのか分からないことである。)
The most、The leastとかは比較されているからAbsoluteに入らないと思います。例:The most common cause of death among teenagers is due to vehicular accidents.
偏見が多いコメント、ややこしくなってすみません。
Abstractです。 Influence of a Diet Very High in Vegetables, Fruit, and Fiber and Low in Fat on Prognosis Following Treatment for Breast Cancer
The Women's Healthy Eating and Living (WHEL) Randomized Trial
JAMA. 2007;298:289-298.
Context Evidence is lacking that a dietary pattern high in vegetables, fruit, and fiber and low in total fat can influence breast cancer recurrence or survival.
Objective To assess whether a major increase in vegetable, fruit, and fiber intake and a decrease in dietary fat intake reduces the risk of recurrent and new primary breast cancer and all-cause mortality among women with previously treated early stage breast cancer.
Design, Setting, and Participants Multi-institutional randomized controlled trial of dietary change in 3088 women previously treated for early stage breast cancer who were 18 to 70 years old at diagnosis. Women were enrolled between 1995 and 2000 and followed up through June 1, 2006.
Intervention The intervention group (n = 1537) was randomly assigned to receive a telephone counseling program supplemented with cooking classes and newsletters that promoted daily targets of 5 vegetable servings plus 16 oz of vegetable juice; 3 fruit servings; 30 g of fiber; and 15% to 20% of energy intake from fat. The comparison group (n = 1551) was provided with print materials describing the "5-A-Day" dietary guidelines.
Main Outcome Measures Invasive breast cancer event (recurrence or new primary) or death from any cause.
Results From comparable dietary patterns at baseline, a conservative imputation analysis showed that the intervention group achieved and maintained the following statistically significant differences vs the comparison group through 4 years: servings of vegetables, +65%; fruit, +25%; fiber, +30%, and energy intake from fat, –13%. Plasma carotenoid concentrations validated changes in fruit and vegetable intake. Throughout the study, women in both groups received similar clinical care. Over the mean 7.3-year follow-up, 256 women in the intervention group (16.7%) vs 262 in the comparison group (16.9%) experienced an invasive breast cancer event (adjusted hazard ratio, 0.96; 95% confidence interval, 0.80-1.14; P = .63), and 155 intervention group women (10.1%) vs 160 comparison group women (10.3%) died (adjusted hazard ratio, 0.91; 95% confidence interval, 0.72-1.15; P = .43). No significant interactions were observed between diet group and baseline demographics, characteristics of the original tumor, baseline dietary pattern, or breast cancer treatment.
Conclusion Among survivors of early stage breast cancer, adoption of a diet that was very high in vegetables, fruit, and fiber and low in fat did not reduce additional breast cancer events or mortality during a 7.3-year follow-up period.
