Table 2.

Adjusted ORs and HRs for the effect of OH on the risk of falling with IPD (one-stage method). The ORs can be interpreted as a measure of the association of OH to falling (the dependent variables). HRs refer to time to first fall incident.

	OR (95% CI) (three studies)	HR (95% CI) (two studies)
OH (Model 1)	0.92 (0.69–1.21) (n = 1022)	1.30 (1.08–1.57) (n = 952)
OH (Model 2)	0.94 (0.70–1.24) (n = 1022)	1.30 (1.08–1.57) (n = 952)
OH (Model 3)	1.21 (0.87–1.68) (n = 954)	1.52 (1.23–1.88) (n = 884)

Model 1, unadjusted. Model 2, adjusted for gender and age. Model 3, adjusted for gender, age, BMI, DM, antihypertensive medication, number of medication and SBP.
