We first excluded indels and SNVs located outside of exon regions following annotation by ANNVAR based on RefSeq gene models (hg19) (Wang et al., 2010).
To identify the use of inpatient tocolysis, we first excluded early pregnancy loss and induced abortion from the hospital discharge file.
We first excluded observations from the Commonwealth of Puerto Rico, which is often done due to different laws and demographic considerations involving the Commonwealth; see "Dimension reduction techniques" section of Young et al. [9] for an example of excluding Puerto Rico.
We first excluded the heterozygous SNPs located close to the centromeres or telomeres described above.
We first excluded probe-sets labeled 'Absent' over all arrays by the Affymetrix software.
As BMI may mediate the relationship between HIV infection and fragility fracture, we first excluded it from these analyses.
To build prediction models based on phase I data, we first excluded 43 of the 96 CpG sites that showed less than 5% median β differences between cases and controls or p-value ≥0.001 (FDR>0.007) in phase I.
We first excluded the subset of all MGC clones where the CDS length was less than 90% of the length of the longest corresponding NCBI RefSeq sequence [12] [14].
We first excluded samples with an indeterminate HIV serology to comply with WHO guidelines when evaluating HIV screening assays, and considered only samples for which we obtained a definite HIV negative or positive status.
We first excluded contamination of inocula by PrPSc not bound to soil: soil-free RML-homogenates were processed as described, and the sedimented fraction applied to N2a-PK1 cells.
To exploit these differences in a multivariate analysis, we first excluded data from one subject and used activity patterns of the voxels from the remaining subjects, together with their score improvements, to train a support vector regression (SVR) algorithm [22], [23].
