Article Title: Association of maternal vitamin D status during pregnancy with bone-mineral content in offspring: a prospective cohort study

doi: 10.1016/S0140-6736(12)62203-X

Figure Lengend Snippet: Mean differences in offspring bone-mineral content in relation to maternal 25(OH)D concentrations in pregnancy, by trimester (A) Offspring total body bone-mineral content (total body less head measured; n=3960). (B) Offspring spine bone-mineral content (n=3196). The p values test whether the association between maternal 25(OH)D concentration and offspring BMC differs by trimester of measurement. Model A adjusted for maternal age and offspring age and sex. Model B, the main confounder-adjusted model, was model A plus adjustment for maternal education, ethnic origin, parity, smoking in pregnancy, and body-mass index before pregnancy. Model C was model B plus adjustment for potential mediation by birthweight, gestational age, and offspring height, lean mass, and fat mass. Model D was model B plus adjustment for potential mediation by offspring 25(OH)D concentrations. Values missing for covariables were calculated by multivariate multiple imputation. 25(OH)D=25-hydroxyvitamin D. Predicted 3rd=all women with 25(OH)D concentrations adjusted to 34 weeks' gestation.

Article Snippet: To increase efficiency and keep selection bias to a minimum, we used multivariate multiple imputation (Stata, version 11 MP2) to impute missing values of covariables for eligible participants, according to the method described by Royston.

Article Title: Implication of Socio-Demographics on Cognitive-Related Symptoms in Sports Concussion Among Children

doi: 10.1186/s40798-016-0058-8

Figure Lengend Snippet: Multivariable log binomial regression model for the effect of race/ethnicity on cognitive-related symptoms

Article Snippet: The significance level for the univariable model was 0.05 (95 % confidence interval), while the significance level for the multivariable model was 0.01 (99 % confidence interval) as to minimize type I error that may result from multiple comparison in the multivariable log binomial regression model. All tests were two-tailed, and the entire analyses were performed using Stata version 13.0 (Stata Corporation, College Station, Texas) [ ].

Article Snippet: For collinear factors such as involvement in high risk sex and having multiple sexual partners, only one was included in the multivariable model. All analyses were done using STATA version 12.
