Abstract

fetched live from OpenAlex

Iron and ferritin are known to have an important role in stroke as well as in other disorders. This prospective study was designed to determine whether administering ferritin levels might help to estimate the severity and prognosis of stroke. Fifty-one patients with a diagnosis of acute stroke were included in the study within 24 h from onset of symptoms. Serum ferritin and cortisol levels were assayed at admission. Clinical status was determined by the Canadian Stroke Scale at admission and on day 21. Serum ferritin level was found to be higher in patients with large lesion size (P < 0.01), deteriorated neurologic status during clinical follow-up (P = 0.03) and deceased patients (P < 0.01). Serum ferritin level was correlated with neurologic deficit (r = 0.50, P < 0.001). No correlation was found between serum cortisol and ferritin levels (r = 0.07, P = 0.7). Serum ferritin level (P = 0.007; OR = 1.02; 95% CI, 1.01-1.03) and large size of lesion (P = 0.021, OR = 11.92; 95% CI; 1.46-197.12) were independently associated with mortality. Increased serum ferritin levels correlate to severity of stroke and the size of the lesion.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
