Effects of a Rehabilitation Program on Perceived Environmental Barriers in Older Patients Recovering from Hip Fracture: A Randomized Controlled Trial

Table 2

The independent and interaction effects of time and group for perceived entrance-related barriers and perceived outdoor barriers derived from the GEE models.

	Perceived entrance-related barriers			Perceived outdoor barriers
	Time	Group	Interaction	Time	Group	Interaction
Model 1	0.003	0.395	0.517	0.189	0.911	0.430
Model 2	0.001	0.303	0.499	0.185	0.793	0.433
Model 3	0.230	0.254	0.396	0.055	0.674	0.548
Model 4	0.211^a	0.665^a	0.467^a	0.049^b	0.439^b	0.528^b
Model 5	0.003	0.315	0.461	0.254	0.456	0.501
Model 6	0.001	0.529	0.493	0.096	0.993	0.500
Model 7	0.003	0.459	0.475	0.164	0.735	0.322

Model 1 is crude model, Model 2 adjusted for demographic (age, gender) and hip-fracture-related variables (time since fracture, number of chronic diseases), Model 3 adjusted for level of physical activity, Model 4 adjusted for ^adifficulty to walk indoors or ^bdifficulty to walk outdoors, Model 5 adjusted for visual acuity, Model 6 adjusted for average outdoor temperature, and Model 7 adjusted for housing-related features.
