Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Objective To study the relation between autoregulation of bilateral posterior cerebral artery flow and cognitive function in patients with basilar artery stenosis.Methods Fifteen patients with basilar artery stenosis were divided into stenosis group without cerebral infaction(n = 9) and stenosis group with cerebral infaction(n = 6).Ten healthy volunteers served as a control group.Autoregulation of bilateral posterior cerebral artery flow was assessed by transcranial Doppler ultrasound breath holding test and oblique test.Executive function,structural skill,auditory, visual and logical memory,information processing speed and visuospatial ability were assayed according to the overall neurophysiolgy test and Montreal cognitive assessment(MCA).Results The information processing speed and visuospatial ability were significantly lower in stenosis group with cerebral infarction than in control group(P0.05).The visuospatial ability was significantly higher in stenosis group with cerebral infarction than in stenosis group without cerebral infarction(P0.05).The breath holding index of posterior cerebral artery and the proportion of anterior and posterior circulating vascular motion reactivity were significantly lower in stenosis group with cerebral infarction and stenosis group without cerebral infarction than in control group (P0.05).The proportion of anterior and posterior circulating vascular motion reactivity was positively related with the visuospatial ability 0=0.830,P0.05).Conclusion Patients with basilar artery stenosis may have cognitive impairment at different severity before cerebral infarction and its hemodynamic change is related with cognitive impairment.

Full frame distilled prediction

Teacher imitation

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.
