Meta-Analysis for Linear and Nonlinear Dose-Response Relations: Examples, an Evaluation of Approximations, and Software
TL;DR: Methods for point and interval estimation of relative risk for log-linear exposure-response relations in meta-analyses of published ordinal categorical exposure- response data have been proposed and the use of 2 publicly available user-friendly programs (Stata and SAS) to implement meta-analysis for dose-response data is illustrated.
Journal ArticleDOI
Calcium intake and hip fracture risk in men and women: a meta-analysis of prospective cohort studies and randomized controlled trials
Heike A. Bischoff-Ferrari,Bess Dawson-Hughes,John A. Baron,Peter Burckhardt,Ruifeng Li,Donna Spiegelman,Bonny Specker,John Orav,John B. Wong,Hannes B. Staehelin,Éilis J. O'Reilly,Douglas P. Kiel,Walter C. Willett +12 more
TL;DR: In this article, the role of total calcium intake in the prevention of hip fracture risk has not been well established, and the authors assess the relation of calciumintaketotheriskofhip fractureonthebasis of meta-analyses of cohort studies and clinical trials.
Journal ArticleDOI
Dietary Calcium and Serum 25-Hydroxyvitamin D Status in Relation to BMD Among U.S. Adults†
Heike A. Bischoff-Ferrari,Heike A. Bischoff-Ferrari,Douglas P. Kiel,Bess Dawson-Hughes,John Orav,Ruifeng Li,Donna Spiegelman,Donna Spiegelman,Thomas Dietrich,Walter C. Willett +9 more
TL;DR: Among men and women, 25(OH)D status seems to be the dominant predictor of BMD relative to calcium intake, and only women with 25( OH)D concentrations <50 nM seem to benefit from a higher calcium intake.
Journal ArticleDOI
Milk intake and risk of hip fracture in men and women: A meta‐analysis of prospective cohort studies
Heike A. Bischoff-Ferrari,Bess Dawson-Hughes,John A. Baron,John A. Kanis,Endel J. Orav,Hannes B. Staehelin,Douglas P. Kiel,Peter Burckhardt,Jana Henschkowski,Donna Spiegelman,Ruifeng Li,John B. Wong,Diane Feskanich,Walter C. Willett +13 more
TL;DR: The conclusion is that in a meta‐analysis of cohort studies, there was no overall association between milk intake and hip fracture risk in women but that more data are needed in men.
Journal ArticleDOI

TL;DR: There was a suggestive, modest positive association for risk of pancreatic cancer for intakes of SSB, and these associations were consistent across levels of sex, smoking status, and body mass index.
