González-Albarrán O, García-Robles R: Correlation between insulin suppression test and quantitative insulin sensitivity check index in hypertensive and normotensive obese patients (Letter). Diabetes Care 24:1998–1999, 2001

On page 1998, in the last sentence of paragraph 2, the formula for QUICKI, “1/log[G₀ + I₀],” should read “1/log[G₀ * I₀].” The sentence containing the correct formula is shown here:

Furthermore, we calculated the insulin sensitivity for each subject with the QUICKI formula: 1/log[G₀ * I₀], where G₀ and I₀ are fasting glucose (mmol/l) and fasting insulin (μUI/ml), respectively; and with the HOMA approach: HOMA=g × i/22.5, where g is fasting glucose (mmol/l), and i is fasting insulin (μUI/ml).
