Table 3: Stepwise multiple regression analysis evaluating factors contributing to LOS ¹ (n=160).

2Model variables	R2	Adjusted R2,3	R2 Change	p value for R2 change
	0.219	0.199
In-hospital hypoglycaemia			0.106	<0.01*

¹ Dependent variable: LOS (log transformed due to positive skewing).

² Variables such as in-hospital hypoglycaemia, inpatient insulin treatment, in-hospital infection, and age were included in the final model.

³ Adjusted for age, in-hospital hypoglycaemia, type of anti-hyperglycaemic treatment—insulin or oral hypoglycaemic agents, in-hospital infections, admission blood glucose level, and intensive care unit admission.

^* p<0.05 indicates the change in R² is statistically significant.

LOS: Length of hospital stay
