What it is good for
Written and checked by a reviewer, not generated from metadata.
No reviewed research questions yet. The measurements and field completeness above are machine-extracted and still useful for judging fit.
What it cannot tell you
Written by a reviewer against the source, not inferred from what is missing.
No reviewed limitations yet. Check the field completeness chart above before committing to an analysis. Low coverage on an endpoint you need is the most common blocker.
Who has used it
Articles that analyzed these data, counted separately from articles that only cited the paper. Only the first counts as reuse.
What articles did with it

METHODS:"PDC000128"), so every dataset in the corpus is counted the same way and the numbers can be compared. The 10 articles listed below were retrieved and graded one at a time, and an article counts as having analyzed the data wherever the accession sits in the analysis - methods, results, tables, figures or supplement - under any of this dataset’s accessions. Read the list as the evidence about these articles, and the count as the number that is comparable across datasets.- Reuse is within the expected range for comparable datasets (index -1.34).

- Open the study in the PDC portalFor people
Proteomic data are released open; the portal's use guidelines still apply. This record spans 4 PDC studies; repeat for each.
https://pdc.cancer.gov/pdc/study/PDC000471 - Accept the data use guidelines and downloadFor people
The portal asks for acknowledgement and citation, not a data access request.
https://pdc.cancer.gov/pdc/data-use-guidelines - Resolve the study UUID, then fetch the file manifestFor agents
filesPerStudy keys on the study UUID, not on PDC000471: called with the pdc_study_id it returns the right number of rows with every column null. Resolve the UUID first and pass the terms acknowledgement.
