Abstract

fetched live from OpenAlex

BACKGROUND: This study aims to explore the impact of transcranial Doppler sonography (TDS) for detecting ischemic stroke (IS). METHODS: PUBMED, EMBASE, Cochrane Library, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, WANGFANG, Chinese Biomedical Literature Database, and China National Knowledge In-frastructure will be utilized to examine case-controlled studies that used TDS for detecting IS. All electronic databases will be searched from inception to March 20, 2020. All study selection, data extraction, and study quality assessment will be carried out by 2 independent reviewers. All study quality will be assessed by Quality Assessment of Diagnostic Accuracy Studies tool, and statistical analysis will be performed by RevMan V.5.3 software and Stata V.12.0 software. RESULTS: This study will explore the impact of TDS for detecting IS through sensitivity, specificity, positive and negative likelihood ratio, and diagnostic odds ratio. CONCLUSION: This study expects to find out whether TDS can be utilized for IS detection.Systematic review registration: INPLASY202040155.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
