New-onset stroke on the risk of hip fracture: the Kailuan cohort study in China

BMC Public Health

Table 2 .Hazard Ratios and 95% Confidence Intervals for the Incidence of hip fracture for Stroke patients Compared With the Matched controls

	Events/Participants (N)	Follow-up duration (PYs)	Incidence rate (per1000 PYs)		Model 1
	Events/Participants (N)	Follow-up duration (PYs)	Incidence rate (per1000 PYs)		HR(95%CI)p value		HR(95%CI)p value			HR(95%CI)p value
Controls	153/33,964	307,200	0.50		1.00		1.00		1.00
Stroke patients	78/8491	69,573	1.12	2.36(1.80–3.02) < 0.001		2.34(1.76–3.10) < 0.001		2.35(1.77–3.12) < 0.001

*Note: HR and 95%CI of hip fractures were calculated in the stroke patients compared to controls; incidence density rate = number of incident cases/person-years × 1000; PY, person-years; HR, hazard ratio. Model 1: adjusted for current smoking, current drinking, high salt diet, physical activity, job nature, income, and BMI. Model 2: adjusted for model 1 plus triglycerides, low-density lipoprotein cholesterol, C-reactive protein, use of antihypertensive drugs, lipid-lowering drugs, and hypoglycemic drugs. Model 3: adjusted for model 2 plus history of myocardial infarction, and history of atrial fibrillation
