When a source changes, the notice travels with it.
PeptideScanner checks DOI-backed publications used in supervised synthesis against a dated Crossref work snapshot. Publisher errata, corrections, expressions of concern, retractions, and reinstatements remain attributed source events—not silent edits or PeptideScanner judgments.
Crossref metadata establishes that this notice is connected to the publication. It does not, by itself, establish what text or result changed or how the source should be interpreted.
Efficacy and safety of setmelanotide, a melanocortin-4 receptor agonist, in patients with Bardet-Biedl syndrome and Alström syndrome: a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial with an open-label period
Crossref metadata establishes that this notice is connected to the publication. It does not, by itself, establish what text or result changed or how the source should be interpreted.
Maintenance of response to oral octreotide compared with injectable somatostatin receptor ligands in patients with acromegaly: a phase 3, multicentre, randomised controlled trial
Crossref metadata establishes that this notice is connected to the publication. It does not, by itself, establish what text or result changed or how the source should be interpreted.
Efficacy and safety of a novel dual GIP and GLP-1 receptor agonist tirzepatide in patients with type 2 diabetes (SURPASS-1): a double-blind, randomised, phase 3 trial
Crossref metadata establishes that this notice is connected to the publication. It does not, by itself, establish what text or result changed or how the source should be interpreted.
Bounded cohort
Every reviewed synthesis publication
Coverage is limited to PubMed sources explicitly selected for the 13 supervised syntheses. It does not yet cover all 1,425 public PubMed bibliography records.
Each accepted PubMed payload supplies the DOI-to-PMID link. PeptideScanner then validates the exact Crossref work DOI, retains the response SHA-256 and Crossref indexing instant, and normalizes only supported updated-by metadata. Repeated entries for the same notice are combined by DOI, type, label, and source while every distinct upstream date remains visible.
Crossref says its REST API exposes metadata deposited by members and trusted sources, including Retraction Watch. The Retraction Watch dataset is updated each working day, but its corrections and expressions-of-concern coverage is not comprehensive. PeptideScanner stores no Crossref abstracts and does not infer the substance or importance of a notice from metadata alone.
