Abstract

BACKGROUND: In patients with type 2 diabetes, the effects of intensive glucose control on vascular outcomes remain uncertain. METHODS: We randomly assigned 11,140 patients with type 2 diabetes to undergo either standard glucose control or intensive glucose control, defined as the use of gliclazide (modified release) plus other drugs as required to achieve a glycated hemoglobin value of 6.5% or less. Primary end points were composites of major macrovascular events (death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke) and major microvascular events (new or worsening nephropathy or retinopathy), assessed both jointly and separately. RESULTS: After a median of 5 years of follow-up, the mean glycated hemoglobin level was lower in the intensive-control group (6.5%) than in the standard-control group (7.3%). Intensive control reduced the incidence of combined major macrovascular and microvascular events (18.1%, vs. 20.0% with standard control; hazard ratio, 0.90; 95% confidence interval [CI], 0.82 to 0.98; P=0.01), as well as that of major microvascular events (9.4% vs. 10.9%; hazard ratio, 0.86; 95% CI, 0.77 to 0.97; P=0.01), primarily because of a reduction in the incidence of nephropathy (4.1% vs. 5.2%; hazard ratio, 0.79; 95% CI, 0.66 to 0.93; P=0.006), with no significant effect on retinopathy (P=0.50). There were no significant effects of the type of glucose control on major macrovascular events (hazard ratio with intensive control, 0.94; 95% CI, 0.84 to 1.06; P=0.32), death from cardiovascular causes (hazard ratio with intensive control, 0.88; 95% CI, 0.74 to 1.04; P=0.12), or death from any cause (hazard ratio with intensive control, 0.93; 95% CI, 0.83 to 1.06; P=0.28). Severe hypoglycemia, although uncommon, was more common in the intensive-control group (2.7%, vs. 1.5% in the standard-control group; hazard ratio, 1.86; 95% CI, 1.42 to 2.40; P<0.001). CONCLUSIONS: A strategy of intensive glucose control, involving gliclazide (modified release) and other drugs as required, that lowered the glycated hemoglobin value to 6.5% yielded a 10% relative reduction in the combined outcome of major macrovascular and microvascular events, primarily as a consequence of a 21% relative reduction in nephropathy.

  • The ACCORD trial found a modest but significant reduction in DPN risk with intensive glucose intervention after 5 years in T2D.

    “The ACCORD trial in individuals with T2D reported a modest but significant DPN risk reduction with intensive glycemia intervention after 5 years of follow-up,69”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [69]

    The paper identifies its trial as ADVANCE (title page, p. 2), not ACCORD. Its secondary-outcomes table (p. 10) reports new or worsening neuropathy in 42.2% of the intensive-control group versus 41.5% of the standard-control group, with a confidence interval spanning no effect. It therefore does not report the claimed significant reduction in DPN risk. (LLM, conf=0.90)

  • The DiRECT Study reported that a very low-calorie formula diet (825-853 kcal/d) followed by stepped food reintroduction achieved remission of type 2 diabetes (HbA1C <6.5% without diabetes medications for at least 2 months) among 46% of participants in the intervention group vs 4% in the control group at 12 months (odds ratio, 19.7 [95% CI, 7.8-49.8]).

    “The DiRECT Study, an open-label, cluster-randomized trial of 306 individuals from 49 primary care practices in the UK, reported that a very low–calorie formula diet (825–853 kcal/d) followed by stepped food reintroduction achieved remission of type 2 diabetes (HbA1C <6.5% without diabetes medications for at least 2 months) among 46% of participants in the intervention group vs 4% in the control”

  • Some newer therapies have a lower hypoglycemia risk, which may allow more people to safely reach individualized A1C targets.

    “As discussed in Q12. How can glycemic targets be achieved in persons with T2D? as well as in the AACE Comprehensive Type 2 Diabetes Management Algorithm,73 some newer therapies carry a lower risk of hypoglycemia, which may enable more persons to safely achieve individualized target A1C levels.69,88–90”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [69]

    The Discussion (p. 13) reports that severe hypoglycemia was relatively uncommon despite the trial’s lower achieved A1C, and less frequent than in an earlier trial. The Results (p. 2) show that the intensive strategy reached an average A1C of 6.5%, but this paper does not establish that newer therapies have a lower hypoglycemia risk or that they enable more people to reach individualized targets safely. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The risks of intensive glycemic control may be avoided by using agents not associated with hypoglycemia, especially in people with frequent severe hypoglycemia, hypoglycemia unawareness, long diabetes duration, advanced atherosclerosis, advanced age, or terminal illness.

    “The potential risks of intensive glycemic control may be obviated by incorporating agents that are not associated with hypoglycemia, especially in persons with frequent severe hypoglycemia, hypoglycemia unawareness, or a very long duration of DM, and particularly in the presence of established and advanced atherosclerosis, advanced age, and terminal illness.69,70,76–81”

  • A relationship between mortality and randomization to intensive glucose control was not observed in ADVANCE or VADT.

    “A relationship between mortality and randomization to intensive glucose control was not observed in ADVANCE or VADT, although VADT was underpowered to explore this relationship.”

    From Hypoglycemia and Diabetes: A Report of a Workgroup of the American Diabetes Association and The Endocrine Society (2013) · cites this paper as [5]

    The ADVANCE Results (p. 2) report no significant difference in death from any cause between intensive and standard glucose control. Our copy does not report mortality findings from VADT or say whether VADT was underpowered to assess that relationship (searched: VADT, Veterans Affairs Diabetes Trial, mortality). (LLM, conf=0.90)

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.
