Using this sample frame, we collected a stratified simple random sample of 9000 people (16 85 years old) and then mailed these people a postal questionnaire (Fig. 1).
Using this sampling strategy, we have established a primary core collection with 150 accessions, and the primary core collection can well represent the genetic diversities of the entire collection.
Using this sampling protocol, we retained all information for subsequent dental anthropological analysis.
Using this sampling method, we previously described the presence of oral fluid HPV-16 IgA and IgG antibodies in the majority of women with cervical neoplasia [ 10].
Using this sampling methodology, we initially selected 64% (n=631) of hospitals in the Midwest region for the comparison group, including all large teaching, large non-teaching, and small teaching hospitals in the region.
Using this sampling frame, we identified eleven states that adopted clean indoor air laws and were able to obtain the records of legislative hearings and floor debates for five of these states: Florida, Louisiana, Oregon, South Dakota, and Utah.
Using this sample-encoding scheme, we implemented a hierarchical clustering of the samples.
Using this Gd2O3 sample, we made an inter-calibration between our system and a magnetic property measurement system (MPMS) that was independently calibrated using a palladium crystal, a paramagnetic rare-earth metal.
Using this random sample we calculated one-sided p-values.
Using this restricted sample, we analyzed the association between DEHP exposure group and creatinine-adjusted urinary MEHP concentrations, and the results were nearly identical to the results from the analyses of unadjusted MEHP levels.
