Results of multivariate linear regression model for time of healing

	Unstandardized beta coefficient	p value	95% confidence interval
Age	0.067	0.026	0.009	0.126
Gap (mm)	0.375	0.011	0.093	0.658

The beta coefficient indicates the factor by which a one-unit increase in the variable increases the outcome. For example, for every 1 year increase in age, the amount of time expected for healing increases by 0.067 months. As a result, healing time was prolonged by approximately 2 days (p = 0.026) for each year of increased age and by 11.25 days (p = 0.011) for each 1 mm increase in fracture
