Stress Hyperglycemia Ratio and Adverse Outcomes in Acute Mild Ischemic Stroke or High-Risk Transient Ischemic Attack: A Secondary Analysis of the INSPIRES Trial
Bibliographic record
Abstract
BACKGROUND: Evidence on the association between the stress hyperglycemia ratio (SHR) and adverse outcomes in patients with mild ischemic stroke (IS) or high-risk transient ischemic attack remains limited. METHODS: This was a secondary analysis of the INSPIRES (Intensive Statin and Antiplatelet Therapy for Acute High-Risk Intracranial or Extracranial Atherosclerosis) randomized clinical trial. SHR was calculated as admission blood glucose (mmol/L) divided by (1.59* HbA1c [%]-2.59). Multivariable Cox regression models were used to assess the association between SHR and adverse clinical outcomes, adjusting for age, sex, and other potential factors. The primary efficacy outcome was any stroke (ischemic or hemorrhagic) within 90 days. Secondary efficacy outcomes comprised composite vascular events, recurrent IS, poor functional outcome, and early neurological deterioration. The primary safety outcome was moderate-to-severe bleeding within 90 days. RESULTS: The INSPIRES trial, ultimately enrolled 6100 patients with mild IS or high-risk transient ischemic attack caused by intracranial or extracranial atherosclerosis, of whom 4515 were included in this secondary analysis. The median age was 65 years (interquartile range, 57-71), and 2894 (64.10%) were male. During the 90-day follow-up, recurrent stroke occurred in 356 patients (7.88%), composite vascular events in 363 (8.04%), recurrent IS in 340 (7.53%), poor functional outcome in 474 (10.51%), and early neurological deterioration in 196 (4.34%). After adjustment for conventional confounders, compared with patients in the lower SHR group (Q1), those with higher SHR levels (Q4) had significantly increased risks of recurrent stroke (hazard ratio [HR], 1.84 [95% CI, 1.30-2.61]), composite vascular events (HR, 1.72 [95% CI, 1.22-2.41]), recurrent IS (HR, 1.79 [95% CI, 1.25-2.55]), poor functional outcome (HR, 1.56 [95% CI, 1.13-2.15]), and early neurological deterioration (HR, 1.62 [95% CI, 1.00-2.61]). In contrast, SHR was not significantly associated with any safety outcomes. CONCLUSIONS: Among patients with acute mild IS or high-risk transient ischemic attack of presumed atherosclerotic cause, elevated SHR levels were independently associated with increased risks of recurrent stroke, composite vascular events, recurrent IS, poor functional outcome, and early neurological deterioration.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
