The gold standard for measuring insulin sensitivity (IS) is the hyperinsulinemic–euglycemic clamp, a time, costly, and labor-intensive research tool. A low insulin sensitivity is associated with a complication-risk in type 1 diabetes. Various formulae using clinical data have been developed and correlated with measured IS in type 1 diabetes. We consolidated multiple formulae into an online calculator (bit.ly/estimated-GDR), enabling comparison of IS and its probability of IS <4.45 mg/kg/min (low) or >6.50 mg/kg/min (high), as measured in a validation set of clamps in 104 adults with type 1 diabetes. Insulin sensitivity calculations using different formulae varied significantly, with correlations (R2) ranging 0.005–0.87 with agreement in detecting low and high glucose disposal rates in the range 49–93% and 89–100%, respectively. We demonstrate that although the calculated IS varies between formulae, their interpretation remains consistent. Our free online calculator offers a user-friendly tool for individual IS calculations and also offers efficient batch processing of data for research.

用于估计 1 型糖尿病胰岛素敏感性的交互式计算器



测量胰岛素敏感性 (IS) 的黄金标准是高胰岛素正常血糖钳夹,这是一种时间、成本高且劳动密集型的研究工具。胰岛素敏感性低与 1 型糖尿病的并发症风险相关。已经开发出使用临床数据的各种公式,并将其与测量的 1 型糖尿病 IS 相关联。我们将多个公式合并到在线计算器 (bit.ly/estimated-GDR) 中,从而可以比较 IS 及其 IS <4.45 mg/kg/min(低)或 >6.50 mg/kg/min(低)的概率(高),根据 104 名 1 型糖尿病成人的一组验证夹测量得出。使用不同公式计算的胰岛素敏感性差异很大,相关性 ( R 2 ) 范围为 0.005-0.87,检测低和高葡萄糖处理率的一致性分别为 49-93% 和 89-100%。我们证明,尽管计算出的 IS 因公式而异,但它们的解释保持一致。我们的免费在线计算器为单独的 IS 计算提供了一个用户友好的工具,还提供了用于研究的高效数据批处理。
