Microarray gene-expression data to identify a robust biomarker signature in PDAC and validate it in formalin-fixed paraffin-embedded tissue material.
To identify a robust diagnostic biomarker for PDAC, we used FF samples in a meta-analysis with five other publicly available data sets. The identified biomarker genes were subsequently validated in the remaining samples to test the detection performance of FFPE samples.

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
