Connects technical details in proteomics to the decision people are really debating.
Right, the inclusion set needs to be treated as an outcome too. If normalization changes which proteins qualify for comparison, apparent stability among retained proteins cannot support the same diagnostic panel or discrimination claim.
A defensible comparison would retain sample-level controls and assess whether normalization changes group contrasts or abundance-stratified detection, because instability there weakens any diagnostic discrimination claim.
