Birth weight, placental weight and methods of delivery were obtained from the obstetric records.
The details regarding gene selection, weighting, and methods required to perform the analysis are reported elsewhere [ 11].
Complex methods, including the use of sampling weights and replication methods for variance estimation, are therefore required for data analysis.
Each logistic regression was also adjusted to take into account of sampling weights and clustering method applied in this survey.
Finally, the porosity was measured by two different methods, namely, the weight and volumetric methods, and the permeability measurement was conducted using Darcy's law.
Weighting and survey methods were used to account for the cluster sampling design.
Pooled RRs were calculated using random effects models, applying inverse variance weighting, and the methods of DerSimonian and Laird [ 15].
The optimal full matching method, on average, offered the best covariate balance compared to stratification and weighting methods for both Bayesian and frequentist propensity score approaches.
RESULTS: Differences in dietary and physical activity were found among adolescents who use extreme weight loss methods and moderate methods, and between dieters and nondieters.
(The women, unlike high-school boys, tend to eschew spit cups and trigger fingers as weight-loss methods, and stick to saunas and salads).
RD contributed to experimental design, pathway and weighting method implementation and statistics, and drafted the manuscript.
