Abstract

fetched live from OpenAlex

Objectives: To investigate the performance of serial Alberta Stroke Program Early CT Score (ASPECTS)assessment for predicting stroke-associated pneumonia (SAP) in patients with thrombolyzedacute anterior circulation ischemic stroke (AACIS). Materials and Methods: A retrospectiveobservational cohort study of adult patients with thrombolyzed AACIS wasconducted. Baseline and 24-hour ASPECTS using non-contrast computed tomography (NCCT), complications of stroke, including SAP and swallowing dysfunctionusing the Modified Water Swallowing test, were collected. Receiver operatingcharacteristic curves using binary logistic regression and a multivariablelogistic regression model were generated to compare the predictive performance.

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.
