To examine this possibility, the same models were analysed while stratifying by gender.
We explored evidence for interaction by repeating logistic and linear models (adjusted for age and current smoking) for Cd, Pb, and Mo while stratifying on potentially protective metals.
We used random-effects Cox proportional hazards models to assess the risk of asthma onset in relation to pollution exposures, while stratifying for age in years and sex in the baseline hazard.
In the second model, we performed logistic mixed model regression analyses, with age and gender as fixed effects and the centre as a random effect, while stratifying for quartile of follow-up length.
In the second model, we performed linear mixed model regression analyses, with age and gender as fixed effects and the centre as a random effect, while stratifying for quartile of follow-up length.
We repeated both risk and outcome analyses while stratifying on calendar time periods, comorbidity levels, age groups, and medical indication for statin use in the main model (1997-2009).
To scratch beneath the surface of Mark Carney & Co's pontificating is to stare into the barrel of a regime that fattens fat pockets while stratifying those it is supposed to represent.
Primary outcomes for the safety behaviors and device use will be assessed while stratifying on the index child age group.
In the final model, we performed logistic mixed model regression analyses, with age, gender, BMI, Charnley classification, indication (OA vs other), and pre-operative SF-36 PCS and MCS as fixed effects and the centre as a random effect, while stratifying for quartile of follow-up length.
The final model consisted of linear mixed model regression analyses, with age, gender, BMI, Charnley classification, indication (OA vs other), and pre-operative SF-36 PCS and MCS as fixed effects and the centre as a random effect, while stratifying for quartile of follow-up length.
