Abstract

fetched live from OpenAlex

The National Health and Nutrition Surveys (NHANES) prepared for the National Heart, Lung and Blood Institute have demonstrated a dramatic decline in both age-adjusted mortality rates from coronary heart disease and stroke since the early 1970s. Concurrently, there has been a steady and dramatic increase in the prevalence of end-stage renal failure requiring renal replacement therapy (all modalities of dialysis and renal transplantation) and the incidence of end-stage renal failure attributed to hypertensive nephrosclerosis reported by the United States Renal Data System (USRDS) and by the Canadian Organ Replacement Registry (CORR) since the early 1980s. Antihypertensive medication prescribing practices of physicians have evolved since the 1980s and through the 1990s, with interesting changes in reported antihypertensive medication prescription behaviours of physicians which correlate to changes in the incidence of hypertensive end-stage renal disease. The rate of increase in the incidence of end-stage renal disease attributed to hypertensive nephrosclerosis has attenuated in the latter half of the 1990s. Possible explanations for this trend as reflected by physician prescribing behaviours, particularly an increase in the use of calcium channel blockers, angiotensin receptor blockers and angiotensin converting enzyme inhibitors compared to a plateau in reliance upon beta-blockers and diuretics, are discussed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
