Abstract

BACKGROUND: Despite improving evidence-based practice following clinical guidelines to optimise drug therapy, Type 2 diabetes (T2DM) still exerts a devastating toll from vascular complications and premature death. Biochemical remission of T2DM has been demonstrated with weight loss around 15kg following bariatric surgery and in several small studies of non-surgical energy-restriction treatments. The non-surgical Counterweight-Plus programme, running in Primary Care where obesity and T2DM are routinely managed, produces >15 kg weight loss in 33% of all enrolled patients. The Diabetes UK-funded Counterpoint study suggested that this should be sufficient to reverse T2DM by removing ectopic fat in liver and pancreas, restoring first-phase insulin secretion. The Diabetes Remission Clinical Trial (DiRECT) was designed to determine whether a structured, intensive, weight management programme, delivered in a routine Primary Care setting, is a viable treatment for achieving durable normoglycaemia. Other aims are to understand the mechanistic basis of remission and to identify psychological predictors of response. METHODS/DESIGN: Cluster-randomised design with GP practice as the unit of randomisation: 280 participants from around 30 practices in Scotland and England will be allocated either to continue usual guideline-based care or to add the Counterweight-Plus weight management programme, which includes primary care nurse or dietitian delivery of 12-20weeks low calorie diet replacement, food reintroduction, and long-term weight loss maintenance. Main inclusion criteria: men and women aged 20-65 years, all ethnicities, T2DM 0-6years duration, BMI 27-45 kg/m(2). Tyneside participants will undergo Magnetic Resonance (MR) studies of pancreatic and hepatic fat, and metabolic studies to determine mechanisms underlying T2DM remission. Co-primary endpoints: weight reduction ≥ 15 kg and HbA1c <48 mmol/mol at one year. Further follow-up at 2 years. DISCUSSION: This study will establish whether a structured weight management programme, delivered in Primary Care by practice nurses or dietitians, is a viable treatment to achieve T2DM remission. Results, available from 2018 onwards, will inform future service strategy. TRIAL REGISTRATION: Current Controlled Trials ISRCTN03267836 . Date of Registration 20/12/2013.

  • Both excess weight and higher glucose exert their effects through aggregated exposure.

    “as both excess weight and higher glucose exert their effects through aggregated exposure. 15,16”

    From 5-year follow-up of the randomised Diabetes Remission Clinical Trial (DiRECT) of continued support for weight loss maintenance in the UK: an extension study (2024) · cites this paper as [16]

    The Discussion (page not available) describes younger people with severe obesity as facing potentially many years of hyperglycaemia and weight-related problems, supporting a concern about prolonged exposure. It does not explicitly say that both excess weight and higher glucose exert their effects through aggregated exposure. (LLM, conf=0.75)

  • Bariatric surgery has dominated discussions of type 2 diabetes remission as the most effective way of producing major weight loss.

    “Bariatric surgery has dominated discussions of type 2 diabetes remission as the most effective way of producing major weight loss.8,9,10”

    From Primary care-led weight management for remission of type 2 diabetes (DiRECT): an open-label, cluster-randomised trial (2018) · cites this paper as [10]

    The Background and Discussion describe bariatric surgery as a way to achieve substantial weight loss and type 2 diabetes remission, and note that guidelines recommend it for obese patients with type 2 diabetes. They do not say it dominated discussions of remission or establish it as the most effective way to produce major weight loss; the paper also describes substantial weight loss through non-surgical diets. The indexed passages provide section labels but no page numbers. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The overall loss to follow up of 14.1% over 2 years is modest for a weight loss study in real-life conditions.

    “the overall loss to follow up of 14·1% over 2 years is modest for a weight loss study in real-life conditions. 14”

    From Durability of a primary care-led weight-management intervention for remission of type 2 diabetes: 2-year results of the DiRECT open-label, cluster-randomised trial (2019) · cites this paper as [14]

    The Sample size section estimates 25% participant dropout within 12 months; it does not report an observed loss to follow-up. I searched for 14.1% and two-year attrition, but the protocol provides no two-year follow-up result or assessment that such a rate is modest. (LLM, conf=0.78)

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.
