devries2021-hit-dnastar false-negative-count (PCR-positive hits not reported)

Tested configuration
DNAstar as run by an ENNGS laboratory (de Vries et al. 2021)
Protocol
Virus hits against RT-PCR: true and false positives, PPV and hit-level sensitivity (de Vries et al. 2021 Supplementary Table 4)
Dataset
ENNGS benchmark: 13 clinical metagenomic datasets with RT-PCR results (de Vries et al. 2021)
Procedure
rna-pathogen-20261009-protocol-devries2021-hit-level
Evaluation
DNAstar: virus hits against RT-PCR (ENNGS)

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
No split
Adaptation
Each laboratory's own database and reporting criteria
Scoring implementation
Organisers' scoring of reported hits against RT-PCR

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.

Evidence table

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.

Audit details

Extracted by deterministic parse of the pinned XLSX cell XML (extract/extract_rna_pathogen.py), with row and column labels asserted. printed_value is the cell text, or the shortest decimal that round-trips to the stored number; displayed spreadsheet formatting was not applied. Pending independent review. Independent review 2026-10-09: value and identity match the source.

review
method: source-hash-verification; deterministic-table-parse; independent-cell-check; reviewer: claude; reviewer note: Separate Claude review agent, independent of the extractor; no human review claimed; date: 2026-10-09; artifact sha256: be0ea61fcffe8ea580077467ca19ef1ac39e88bbc82d916bc65b58a6683214f6; retrieval url: https://www.medrxiv.org/content/medrxiv/early/2021/05/08/2021.05.04.21256618/DC1/embed/media-1.xlsx; method note: Re-downloaded the workbook and matched its SHA-256. Read de Vries et al. Supplementary Tables 2 and 4 (medRxiv v1 workbook) with a separate stdlib OOXML reader written for this review (the extractor's script was not run). Checked printed and numeric value, locator, metric, unit and direction from the headers, and the evaluation's configuration, protocol and dataset. Recomputed PPV, sensitivity, TP + FN and TP + FP for every row.; note: Extracted by deterministic parse of the pinned XLSX cell XML (extract/extract_rna_pathogen.py), with row and column labels asserted. printed_value is the cell text, or the shortest decimal that round-trips to the stored number; displayed spreadsheet formatting was not applied.
