Physical Activity In Renal Disease (PAIRED) and the effect on hypertension: study protocol for a randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: The prevalence of hypertension among people with chronic kidney disease is high with over 60% of people not attaining recommended targets despite taking multiple medications. Given the health and economic implications of hypertension, additional strategies are needed. Exercise is an effective strategy for reducing blood pressure in the general population; however, it is not known whether exercise would have a comparable benefit in people with moderate to advanced chronic kidney disease and hypertension. METHODS: . A total of 160 participants will be randomized, with stratification for estimated glomerular filtration rate, to a 24-week, aerobic-based exercise intervention or enhanced usual care. The primary outcome is the difference in 24-h ambulatory systolic blood pressure after 8 weeks of exercise training. Secondary outcomes at 8 and 24 weeks include: other measurements of blood pressure, aortic stiffness (pulse-wave velocity), change in the Defined Daily Dose of anti-hypertensive drugs, medication adherence, markers of cardiovascular risk, physical fitness (cardiopulmonary exercise testing), 7-day accelerometry, quality of life, and adverse events. The effect of exercise on renal function will be evaluated in an exploratory analysis. The intervention is a thrice-weekly, moderate-intensity aerobic exercise supplemented with isometric resistance exercise delivered in two phases. Phase 1: supervised, facility-based, weekly and home-based sessions (8 weeks). Phase 2: home-based sessions (16 weeks). DISCUSSION: To our knowledge, this study is the first trial designed to provide a precise estimate of the effect of exercise on blood pressure in people with moderate to severe CKD and hypertension. The findings from this study should address a significant knowledge gap in hypertension management in CKD and inform the design of a larger study on the effect of exercise on CKD progression.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
