Population sample weights were then constructed to take into account the probabilities of selection in the stratified sample design and to adjust for differential nonparticipation [ 3].
Logistic regression analysis was performed in Stata SE V.11.1 (Stata Corporation, Texas, USA) using survey commands with sampling and non-response weights to allow for the clustered, stratified sample design and to adjust for non-response at baseline and attrition between the study years.
Studies that fell into the top tertile of the quality score tended to employ quantitative physical activity assessments, to investigate recreational activity, to examine recent physical activity, to use a cohort design, and to adjust for smoking, obesity, hypertension, and diabetes.
Appropriate sampling weights were constructed for the national database and applied to seroprevalence data to account for the complex sampling design [29] [31] and to adjust for age and community setting (capital, urban, rural) which were not representatively sampled.
This study then can provide port policy makers with a helpful tool to derive ex-ante MES level at the terminal designing stage and to adjust ex-post port investment decisions at the additional port capacity designing stage, which may contribute to avoiding overcapacity.
Furthermore, exploration of the mode of action of a drug is always an iterative process: responses to initial protocols are used to design new protocols, and to adjust parameters of the protocols to individual drugs.
On the other hand, the strength of our study is that previous studies [ 11, 34, 48] for the relationship between habitual substance use and the risk of ESCC from the same area of Taiwan provide us adequate information to well design the questionnaire and to adjust the influence from those potential confounding factors.
Reviewing students' reading responses allowed me to identify and reach out more promptly to students falling behind, to identify topics that piqued student interest or required additional review, and to adjust question design to further the efficacy of the solution.
In an agreement signed with the New Jersey Department of Environmental Protection on Jan . 6 Hartz Mountain Industries, the builder, agreed to shift the positions of two buildings it wanted to build just below the final loop of the road into the toll plaza, and to adjust the design of one of them, to keep all but a sliver of the view open.
The simplified conjugate gradient method was used as an optimizer to obtain the optimal performance, and to adjust the design variables, i.e. product air flow rate and working-to-product air flow ratio.
In contrast, studies in the bottom tertile of the quality score tended to employ qualitative physical activity assessments, to investigate occupational activity, to examine past physical activity, to use a case control design, and to not adjust for smoking, obesity, hypertension, or diabetes.
