Table 2 summarizes the distribution of HIV prevalence, and multi-variable analysis results of selected baseline characteristics.
From variable selection analysis results (Supplementary Table 1), it was apparent that although aldosterone and CRP levels were linearly related to incidence of MetS, BNP quartiles were not.
While MART® is powerful in selecting non-redundant prognostic variables from a large set of highly interactive variables, CART analysis results in simple algorithms, and more easily understood "decision trees", that are used in the medical literature [28].
According to patient-related variables, multivariate analysis results demonstrated that noncurrent smokers were associated with nonresponse to MTX.
Each article is analyzed using the following criteria: study objectives, data sources, outcome variables, primary predictor variables, confounders, statistical analysis, results, established knowledge, and shortcomings.
The duration of each game play, expenses, other dominant behavioral variables, and factor analysis results used to evaluate game dependence were subsequently examined.
19 This would bias the instrumental variable analysis towards the null results seen in the multivariable analysis.
51 Strengths of our study include a large population size, with sufficient statistical power to detect an association of 25-hydroxyvitamin D lowering genotypes with mortality; the fact that our instruments were strong (F>>10) for instrumental variable analysis; and that the results were robust in sensitivity analyses.
The observed differences on perceived quality between facilities remained significant after adjusting for the effects of socio-demographic and client-related variables by multiple regression analysis; results of which are provided in Additional file 3: Table S3.
For this reason, we investigated whether inclusion or exclusion of individual variables (using the "jackknife by variables" technique), and groups of variables (using the "bootstrap by variables technique") materially affect the analysis results.
