Analysis of hospital-based stroke registry in a neurological centre in Kolkata.
Bibliographic record
Abstract
This was a retrospective analysis of 7-year (January 1995-December 2001) hospital-based in-patient medical records of stroke cases (subarachnoid haemorrhage excluded) who arrived from various parts of West Bengal. The total number of cases was 801 out of whom 792 had neuro-imaging. There were 399 caes of intracerebral haemorrhage (ICH) and 393 cases of cerebral infarct (CI). The CI: ICH ratio was 0.98. Less than 25% patients reached hospital within 3 hours of stroke onset. Twenty-nine per cent of cases presented with mild stroke (Canadian stroke score > 8.5). Hypertension was observed in 77.3% of ICH cases. The striking finding of this study was a remarkably high number of ICH among the admitted patients. This indicates the need of population-based studies to be conducted at different parts of West Bengal to determine whether them is truly a high prevalence and incidence of ICH in this Indian state.

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.
