Gary Crigger, Firestone's executive vice president for business planning, testified before a Senate subcommittee on Wednesday that the company's safety program relied on warranty data, quality tests at factories and field research into the performance of tires in use.
Only those genes passing the data quality tests were analyzed here (i.e. 10 genes), see Table 1.
A series of data quality tests were applied to exclude data points that clearly indicate compromised samples, while retaining the natural variability in the dataset.
For the convenience of the research community we have created a user-friendly R software package called wateRmelon, downloadable from bioConductor, compatible with the existing methylumi, minfi and IMA packages, that allows others to utilize the same normalization methods and data quality tests on 450K data.
This study compared the German and US TQOLITv1 in terms of data quality, tests of assumptions underlying scale construction and scoring, reliability and evidence of validity based on a conceptual framework of hypothesized relationships among smoking status and CPD, biomarkers of exposure, smoking-specific symptoms and QOL impact as well as generic QOL measures.
We took advantage of the possibility of comparing downstream genotype calls from the 1000 Genomes and HLA typing based on Sanger sequencing for the same set of samples to assess data quality and test hypothesis about possible biases.
The responsibilities of the SCC include: 1. Planning and conducting the study designing the protocol; designing the CRF; designing the operation guide; managing and controlling data quality; designing, testing and maintaining the electronic database; data quality control; assisting the steering committee; 2.
To ensure data quality, pre-test was done in one district which was not included in the main study.
Of these 184 genes, 68 passed our data quality control tests, thus allowing us to compare these genes to our NMD-regulated candidates.
Before relying on such data for surveillance purposes, it is first necessary to evaluate: 1) the availability of routine PMTCT program data; 2) differences in test results between the PMTCT and ANC surveillance programs; and 3) any bias that may be introduced by differences in uptake, data quality, and testing procedures between these data sources.
