hou2024-s3-ifs-mathios-ind sensitivity-at-95-percent-specificity (lung cancer vs healthy; independent validation)
- Tested configuration

- Protocol
- Hou et al. 2024 independent validation, Mathios et al. independent lung cohort (Table S3)
- Dataset
- Mathios et al. 2021 independent lung cohort, 46 lung cancer and 385 healthy (as used by Hou et al. 2024)
- Procedure
- ctdnafrag-20261009-protocol-hou2024-mathios-independent
- Evaluation
- IFS (open chromatin), independent validation on Mathios et al. independent dataset (LUNG)
- Coverage
- Not reported scored / Not reported eligible
- Uncertainty
- Not reported by the source
- Evidence
- Author-reported evaluation · source checkedSystematically Evaluating Cell-Free DNA Fragmentation Patterns for Cancer Diagnosis and Enhanced Cancer Detection via Integrating Multiple Fragmentation Patterns; Hou et al. 2024, Supporting Information workbook (Tables S1-S15) · Supporting Information sheet S3, D30; data set 'Mathios et al. independent dataset (LUNG)'; row 'IFS'; column 'Sensitivity @95% specificity'
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
- Independent validation (trained on another cohort)
- Adaptation
- SVM trained on the training cohort, applied unchanged
- Scoring implementation
- Not reported
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.

Read the cell with a separate stdlib OOXML reader written for this review (shared strings, raw cell text, and the number format from styles.xml, General for every extracted cell); the extractor's scripts were not imported or run. Built each cell's identity from the sheet title, header row and row labels, then checked raw text, printed value (shortest round-trip decimal, or the leading number of a text cell), numeric value, interval, metric, qualifier, unit, direction, denominator, and the linked evaluation's configuration, protocol and dataset.; reviewer: claude; reviewer note: Separate Claude review agent, independent of the extractor; no human review claimed; date: 2026-10-09; artifact sha256: 41b24f7e6bcb9bea6127a249127a4c4d53e8ea42b50e95242054791511695fb0; retrieval url: https://pmc-oa-opendata.s3.amazonaws.com/PMC11321639.1/ADVS-11-2308243-s001.xlsx; note: Extracted by deterministic parse of the pinned XLSX cell XML (extract/rawxlsx.py) with sheet title, header and row labels asserted.
