Abstract
The impact of remote limb ischemic conditioning on poststroke cognitive impairment was evaluated with 104 first-time patients of noncardiac ischemic stroke. During the acute phase the patients were randomized into control and remote limb ischemic conditioning groups. Both groups received standard treatment, while the remote limb ischemic conditioning group received additional remote limb ischemic conditioning treatment for 6 months. All participants underwent neuropsychological evaluation, transcranial Doppler detection, P300 event-related potential and brachial-ankle pulse wave velocity measurements, and determination of serum intercellular adhesion molecule-1 and endothelin-1 levels both at admission and 6 months poststroke. The number of cases with poststroke cognitive impairment in each group was evaluated 6 months poststroke. No statistically significant difference was found in demographic data or baseline detection indices at admission between the two groups. However, at 6 months poststroke, the remote limb ischemic conditioning group had significantly higher total Montreal Cognitive Assessment score and its domains of visuospatial and executive functioning and attention scores, significantly lower activity of daily living scale score, shorter P300 latency, and higher amplitude compared with the control group. Moreover, the middle cerebral artery, average blood flow velocity was significantly higher, while the middle cerebral artery-pulsation index, basilar artery pulsation index, and the levels of brachial-ankle pulse wave velocity, intercellular adhesion molecule-1, and endothelin-1 were significantly lower in the remote limb ischemic conditioning group compared with the control group. These results demonstrate that remote limb ischemic conditioning causes a significant improvement in cognitive domains, such as visuospatial and executive functioning and attention, and is therefore linked with reduced incidence of poststroke cognitive impairment.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
