Blood Pressure Targets for Older Patients—Do Advanced Age and Frailty Really Not Matter?
Bibliographic record
Abstract
In 2017, Hypertension Canada removed advanced age and frailty as considerations for caution when deciding on intensive therapy in their guidelines for the diagnosis, risk assessment, prevention, and treatment of hypertension in adults. Dementia is not mentioned. In this commentary, we review why advanced age and frailty were removed, and examine what is currently known about the relationship between hypertension and both incident and prevalent dementia. We make the case that the presence of frailty (especially when severe) and dementia should be considered when deciding on intensive therapy in future iterations of Hypertension Canada guidelines.

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.
