Table 23: Summary of GRADE Quality Assessment for Devices^*.

Intervention	No. of Studies	Quality Assessment				Summary of Findings
							No. of Patients		Effect (RR [95% CI])
		Design	Quality	Consistency	Directness	Other	Interv	Control		Quality
Hip Protector	1	RCT	Serious limitations†	Only 1 study	Some uncertainty about directness‡	None	139	140	3.49 (0.68–17.97)	Low
		High	Moderate	Moderate	Low	Low
Gait-stabilizing device	1	RCT	Serious limitations§	Only 1 study	Some uncertainty about directness║	Strong evidence of association	55	54	0.43 [0.29–0.64]	Moderate
		High	Moderate	Moderate	Low	Moderate

^*RR refers to relative risk; CI, confidence interval; Interv, intervention; RCT, randomized controlled trial

^†High dropout in hip protector group; randomization technique not described. (82)

^‡Study population of people with previous hip fracture, therefore may not be generalizable to all seniors. (82)

^§No information as to whether groups comparable at study entry. (80)

^║No information on number of people excluded because they couldn’t put on device. This may affect the generalizability and use in the general ambulatory, elderly population. (82)
