Effects of Blood Pressure Lowering on Clinical Outcomes According to Baseline Blood Pressure and Cardiovascular Risk in Patients With Type 2 Diabetes Mellitus
Bibliographic record
Abstract
The optimal blood pressure (BP) goal in patients with diabetes mellitus remains controversial. We examined whether benefits and risks of intensified antihypertensive therapy in diabetes mellitus are influenced by either baseline BP or cardiovascular disease (CVD) risk. We studied 10 948 people with diabetes mellitus, at moderate-to-high risk, in the ADVANCE trial (Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation). Cox models were used to determine whether baseline BP category or CVD risk modified the outcomes of combination perindopril-indapamide treatment, compared with placebo. During 4.3 years of follow-up, treatment with perindopril-indapamide versus placebo reduced mortality and major vascular (macrovascular or microvascular) events. There was no evidence of differences in these effects, regardless of baseline systolic BP (evaluated down to <120 mm Hg; P for heterogeneity, 0.85), diastolic BP (evaluated down to <70 mm Hg; P=0.49), or whether 10-year CVD risk was ≥20% or <20% ( P=0.08). The effects of randomized treatment on discontinuation of treatment because of cough or hypotension/dizziness were also statistically consistent across subgroups defined by baseline BP and CVD risk (all P ≥0.08). Adults with diabetes mellitus appear to benefit from more intensive BP treatment even at levels of BP and CVD risk that some guidelines do not currently recommend for intervention.

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.
