Table 3 Parameter estimates from the LASSO and estimated proportion of variance explained

From: Development and validation of a predictive model of acute glucose response to exercise in individuals with type 2 diabetes

Variable Coefficient Proportion of variance explained*
  (Development dataset) (Bootstrap derived 95% CI1)
Pre-exercise glucose* -0.46 30.6 (13.6-45.2)
Minutes since eating 0.002 7.9 (3.2-17.2)
Non linear minutes since eating (range -1 to 1) -0.1 4.9 (2.6-10.3)
Hemoglobin A1c 0.24 3.6 (1.7-13.3)
Postprandial status 1.2 3.2 (1.9-8.1)
Exercise duration* -0.024 1.7 (0.7-9.1)
Percentage of maximum heart rate* 1.83 1.5 (0.3-11.0)
Sulfonylurea -0.2 1.0 (0.2-6.2)
Age -0.004 0.8 (0.2-7.9)
Exercise session number -0.06 NA**
  1. 1. CI Confidence Interval* These variables were unpenalized in the LASSO **Since the LMG algorithm does not account for repeated measures, only data from the first exercise session was used and therefore the relative contribution of this variable could not be assessed.
