UK Prospective Diabetes Study Group,·1998·BMJ

Abstract

Objective: To determine whether tight control of blood pressure prevents macrovascular and microvascular complications in patients with type 2 diabetes. Design: Randomised controlled trial comparing tight control of blood pressure aiming at a blood pressure of <150/85 mm Hg (with the use of an angiotensin converting enzyme inhibitor captopril or a β blocker atenolol as main treatment) with less tight control aiming at a blood pressure of <180/105 mm Hg. Setting: 20 hospital based clinics in England, Scotland, and Northern Ireland. Subjects: 1148 hypertensive patients with type 2 diabetes (mean age 56, mean blood pressure at entry 160/94 mm Hg); 758 patients were allocated to tight control of blood pressure and 390 patients to less tight control with a median follow up of 8.4 years. Main outcome measures: Predefined clinical end points, fatal and non-fatal, related to diabetes, deaths related to diabetes, and all cause mortality. Surrogate measures of microvascular disease included urinary albumin excretion and retinal photography. Results: Mean blood pressure during follow up was significantly reduced in the group assigned tight blood pressure control (144/82 mm Hg) compared with the group assigned to less tight control (154/87 mm Hg) (P<0.0001). Reductions in risk in the group assigned to tight control compared with that assigned to less tight control were 24% in diabetes related end points (95% confidence interval 8% to 38%) (P=0.0046), 32% in deaths related to diabetes (6% to 51%) (P=0.019), 44% in strokes (11% to 65%) (P=0.013), and 37% in microvascular end points (11% to 56%) (P=0.0092), predominantly owing to a reduced risk of retinal photocoagulation. There was a non-significant reduction in all cause mortality. After nine years of follow up the group assigned to tight blood pressure control also had a 34% reduction in risk in the proportion of patients with deterioration of retinopathy by two steps (99% confidence interval 11% to 50%) (P=0.0004) and a 47% reduced risk (7% to 70%) (P=0.004) of deterioration in visual acuity by three lines of the early treatment of diabetic retinopathy study (ETDRS) chart. After nine years of follow up 29% of patients in the group assigned to tight control required three or more treatments to lower blood pressure to achieve target blood pressures. Conclusion: Tight blood pressure control in patients with hypertension and type 2 diabetes achieves a clinically important reduction in the risk of deaths related to diabetes, complications related to diabetes, progression of diabetic retinopathy, and deterioration in visual acuity.

  • Hypertension is more prevalent in people with T2D than in the general population, and hypertension predicts progression to T2D.

    “Hypertension is not only more prevalent in persons with T2D than in the general population, but hypertension also predicts progression to T2D.”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [182]

    The Introduction states that hypertension is more prevalent in people with type 2 diabetes than in the general population. It describes hypertension as a risk factor for microalbuminuria and retinopathy, not as a predictor of progression to type 2 diabetes. Searches for that prediction and for new-onset diabetes found no supporting passage. (LLM, conf=0.89)

  • Antihypertensive therapy reduces the risk of albuminuria.

    “Antihypertensive therapy reduces the risk of albuminuria (67)(68)(69)(70), and among people with type 1 or 2 diabetes with established CKD (eGFR <60 mL/min/1.73m 2 and UACR $300 mg/g creatinine), ACE inhibitor or ARB therapy reduces the risk of progression to ESKD (71)(72)(73)(74)(75)(76)(77)(78)(79)(80).”
  • Antihypertensive therapy reduces the risk of albuminuria.

    “Antihypertensive therapy reduces the risk of albuminuria (68-71), and among people with type 1 or 2 diabetes with established CKD (eGFR <60 mL/min/1.73m 2 and UACR ≥300 mg/g creatinine), ACE inhibitor or ARB therapy reduces the risk of progression to kidney failure (72)(73)(74)(75)(76)(77)(78)(79)(80)(81).”
  • In the UKPDS trial, intensive blood pressure management in people with type 2 diabetes reduced the risk for heart failure by 56%.

    “in the UK Prospective Diabetes Study (UKPDS) trial, intensive blood pressure management in people with type 2 diabetes reduced the risk for heart failure by 56% (276).”
  • In the UKPDS trial, intensive blood pressure management in people with type 2 diabetes reduced the risk for heart failure by 56%.

    “For example, in the UK Prospective Diabetes Study (UKPDS) trial, intensive blood pressure management in people with type 2 diabetes reduced the risk for heart failure by 56% (273).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
