Adjusted Odds Ratios and 95% Confidence Intervals (n=1702 ankles^*) for exploratory associations between covariates and KLG 1 or more

Characteristic	Odds Ratio¹ (95% Confidence Interval)	Adjusted Odds Ratio² (95% Confidence Interval)
Characteristic	Odds Ratio¹ (95% Confidence Interval)	Adjusted Odds Ratio² (95% Confidence Interval)	Age ≥ 70 years	0.81 (0.64, 1.03)	0.86 (0.68, 1.09)
Age < 70 years	referent	referent
BMI ≥ 30 kg/m²	2.00 (1.58, 2.52)^†	2.13 (1.66, 2.73)^†
BMI < 30 kg/m²	referent	referent
Women	0.49 (0.38, 0.64)^†	0.47 (0.36, 0.61)^†
Men	referent	referent
African-American	0.83 (0.65, 1.06)	0.75 (0.58, 0.98)^†
Caucasian	referent	referent
Ankle injury	1.57 (1.06, 2.31)^†	1.50 (1.02, 2.22)^†
No injury	referent	referent
Ankle symptoms	1.82 (1.32, 2.51)^†	1.64 (1.18, 2.29)^†
No ankle symptoms	referent	referent

n=864 individuals/1728 ankles; missing data on injury (10 individuals/20 ankles), symptoms (1 individual/2 ankles), or KLG (4 ankles) results in 1702 ankles available for complete case analysis.

Odds Ratio¹: adjusted only for intra-person correlation using generalized estimating equations

Odds Ratio²: adjusted for intra-person correlation and all other listed covariates
