Description
New in R8. QCd metabolomics data (final) for phosphatidylcholine diacyl C421 - Metabolomics measures in a relative scale (uM) - validity=0 and LoD=0.008 based on Biocrates report - processed for analysis use -derived by 2-step QC process from raw variable pcaac421. Assayed in MRC HNR lab on plasma using Liquid Chromatography Mass Spec with batch correction via location-scale method after 1) normalisation of a Box-Cox type and 2) winsorisation based on overall mean +/- 5 x batch-specific standard deviation - see the Fenland document on metabolomics for more details) Raw var is PCaaC421_raw and QCstep1 var is PCaaC421_i
