False negatives (sequencing negative, comparator positive; organism level; organisms: all organisms; reference: clinical microbiological tests (CMT)) of MGISEQ-200 short-read mNGS workflow (Hu et al. 2026) on 62 residual BALF specimens with culture results (Hu et al. 2026)
5 False negatives (sequencing negative, comparator positive; organism level; organisms: all organisms; reference: clinical microbiological tests (CMT))
Methods

- Coverage
- Not reported scored / Not reported eligible
- Uncertainty

- Evidence
- Author-reported evaluation · source checkedBenchmarking next- versus third-generation sequencing in metagenomics: performance metrics and diagnostic efficacy · Table 2, block "NGS", column group "Clinical microbiological tests (CMT)", row "−" (sequencing negative), column "＋" (comparator positive)
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
- Single clinical set
- Adaptation
- Workflow as stated per configuration
- Scoring implementation
- Organism-level 2x2 counts; PPA and NPA
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.
