Dietary patterns associated with fall-related fracture in elderly Japanese: a population based prospective study

Results
Among 877 participants who agreed to a 4 year follow-up, 28 suffered from a fall-related fracture. Three dietary patterns were identified: mainly vegetable, mainly meat and mainly traditional Japanese. The moderately confirmed (see statistical methods) groups with a Meat pattern showed a reduced risk of fall-related fracture (Hazard ratio = 0.36, 95% CI = 0.13 - 0.94) after adjustment for age, gender, BMI and energy intake. The Vegetable pattern showed a significant risk increase (Hazard ratio = 2.67, 95% CI = 1.03 - 6.90) after adjustment for age, gender and BMI. The Traditional Japanese pattern had no relationship to the risk of fall-related fracture.

とあるように,877人中28ケースしか骨折がないので,当然,standard errorは大きくなるよねぇ,ということで,95% CIも広い(なので,5%で有意ぎりぎり)。

なので,やっぱりメディアの方たちのリテラシーがいまいちだなぁ,と思うわけです。

しかし,久しぶりにCox PHを見られるとは,なつかしー
