To prescribe or not to prescribe? #SGLT2 inhibitors slow #CKD progression but it's unclear who with #T2D and mild/no CKD truly benefits. This new model predicts individual benefit, supporting more targeted prescribing. #PrecisionMedicine link.springer.com/article/10… 🔓@Exeter_Diabetes

The groundbreaking @Exeter_Diabetes 5-drug model accurately predicts the most effective glucose-lowering treatment for individuals with #Type2Diabetes At #EASD2025 we hear that it's been updated to include semaglutide Huge potential to transform #T2D care for millions globally

📢 Can AI help pick the best glucose-lowering drug❓ "Computer says yes" 🔹 Machine-learning model predicts optimal therapy (GLP-1RA, SGLT2i, SU, DPP4i, or TZD) 🔸 Model-concordant Rx = 5.3 mmol/mol ⤵️ HbA1c at 12m vs. non-optimal choices 🔹 Better long-term outcomes: 38% ⤵️ glycaemic failure, 29% ⤵️ renal risk, 15% ⤵️ MACE-HF 🔸 Only 17.8% of UK patients currently get the model-predicted best drug❗️ 👉 Time for AI-driven personalised prescribing in #T2D? 🔗 ggdocs.co/9p2tgf 🔗diabetesgenes.org/t2-treatme…

💥Those of us working in science comms are perhaps too fond of the word "gamechanging" but this research by @john_den_ @athattersley @Exeter_Diabetes, published today in @TheLancet and announced at #DUKPC25, truly deserves that description 💥 #Type2Diabetes #BetterCare
“This tool could mark the most significant advance in type 2 diabetes care in more than a decade, improving health outcomes for millions.” Dr Elizabeth Robertson, Director of Research and Clinical at Diabetes UK. A thread 👇

We found 14 re-analyses that delivered evidence that we considered both credible and clinically important. Many of these were IPDMA, combining databases. Among these 14, there were 10 simple ‘risk modeling’ studies. Interestingly, >half of these showed variation in both absolute AND relative effects across the different risk strata. There were also 4 ‘effect models’, that more flexibly explored treatment interactions with individual variables for subgroup identification, with credible and clinically important results. These 4 have been validated externally. Most 'effect models', however, yielded 'exploratory' results awaiting confirmation--or more likely refutation. 3/x

All models are wrong and yours are useless! In case you missed my talk yesterday on how to make clinical prediction tools useful for patients, you can read all about it here. Enjoy! doi.org/10.1038/s41698-024-0…
