Accuracy (OGBl-ppa PPI link prediction) of NGNN with GCN with ProtTrans protein embeddings (sequence) (PPI embeddings study) on OGBl-ppa PPI graph (embedding study)

0.795 Accuracy (OGBl-ppa PPI link prediction)

Evidence concern: excluded from comparisons

The text's summary does not match the tables: it lists ProtT5 among structure embeddings while the tables print ProstT5; it reports a GraphSAGE with DistMult result (+38% Hits@100 on HuRI) although DistMult is not a column; and the stated gains (for example ESM-2 with GraphSAGE +6% Hits@100 on OGBl-ppa) cannot be reproduced from the printed table values (GS random 0.0104, ESM-2 0.2421). Values are kept as printed; comparisons should rely on the tables only after a reviewer has judged this. Random-feature baselines on OGBl-ppa (GCN 0.0588, GS 0.0104 Hits@100) look far below the public OGB leaderboard values the authors say they reproduced (Supplementary Table S2, not retrieved; reviewer did not verify the leaderboard values).The role of protein embeddings for protein-protein interaction prediction with graph neural networks · Results and discussion, first paragraph; Tables 5 and 6

Evidence: Independent external evaluation · source checkedThe role of protein embeddings for protein-protein interaction prediction with graph neural networks · Table 6, block 'OGBl-ppa', row 'N-GCN', column 'ProtTrans'

A source-checked result verifies the numerical transcription, not every model or protocol detail. Evaluation metadata: source checked. Source checked does not mean independently reproduced.

Reproduction

Split: Benchmark test edges
Adaptation: Trained by the study authors
Scoring implementation: Accuracy as printed

No execution recipe has been verified for this exact configuration and evaluation. A benchmark's general instructions may use different inputs, splits or model settings.

Reproducing this published result requires matching its model configuration, data, split and scorer. Source checking or a successful smoke test does not establish score reproduction.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.

Table 6 body row 5. Independent review 2026-10-11: Re-downloaded the PMC full-text XML from the recorded Europe PMC URL and matched its SHA-256.

The misaligned HuRI N-GCN row is laid out the same way in the XML and the PMC HTML, so reading its eleven values in column order is the only consistent reading. Read 42 values covering both tables, both datasets, all seven rows and all eleven columns from the PMC HTML rendering: 42 of 42 match.
