* The adjusted linear regression reported in model 1 is the result of a backward selection model technique applied on a model including all variables that were significant at p ≤ 0.20 in univariate analysis. Instead of the hypoglycemic symptom severity effects it contains an indicator for the experience of hypoglycemic symptoms. In addition to the variables reported above, the resulting model included indicators for Spain, France, UK, Finland, and Germany.
† The adjusted linear regression reported in model 1 is the result of a backward selection model technique applied on a model including all variables that were significant at p ≤ 0.20 in univariate analysis. Instead of the indicator for the experience of hypoglycemic symptoms it contains symptom severity effects with no hypoglycemic symptoms being the reference group. In addition to the variables reported above, the resulting model included indicators for Spain, France, UK, Finland, and Germany.
