Factor	Outcome	OR	95% CI	p value
Age > 25 years	Symptomatic	3.6	(1.3–9.8)	0.01
	Replaced	8.9	(2.6–30.9)	< 0.001
Joint congruency (poor/fair)	Symptomatic	2.0	(0.7–5.7)	0.22
	Replaced	3.2	(0.9–10.6)	0.07
Minimum JSW 2 to 5 mm	Symptomatic	1.8	(0.5–6.6)	0.37

OR = odds ratio; CI = confidence interval; JSW = joint space width.
