Table 3.

Multiple comparison results of the prevalence of radiographic knee OA, knee pain and both radiographic and knee pain between each two groups of non-obese, non-sarcopenic, sarcopenic and obese people.

	Non-obese	Non-sarcopenic	Sarcopenic	Obese
	Non-sarcopenic vs. sarcopenic	Non-obese vs. obese	Non-obese vs. obese	Non-sarcopenic vs. sarcopenic
Radiographic knee OA	0.922	< 0.001	< 0.001	0.467
Knee pain	0.981	0.658	< 0.001	0.118
Radiographic knee OA & knee pain	0.932	0.098	< 0.001	0.298

Radiographic knee OA, Kellgren-Lawrence grade scale grade ≥ 2; Knee pain, knee pain for 30 days over the past 3 months.

Post-hoc corrections of ANOVA by Bonferroni’s method was done; p-value smaller than 0.0083 is statistically significant.
