Table 2.

Comparison of change in medial JSW and ME between OA and non-OA study participants.

	OA (median, 95% CI)	Non OA (median, 95% CI)	p Value
Change in Medial JSW
Obs 1	0.4 (0.1–0.7) mm	0.2 (0.1–0.3) mm	p = 0.015
Obs 2	0.5 (0.2–0.8) mm	0.4 (0.3–0.5) mm	p = 0.020
Obs 3	0.6 (0.4–0.8) mm	0.3 (0.2–0.5) mm	p = 0.001
Average	0.5 mm	0.3 mm	p = 0.008
Change in ME
Obs 1	1.0 (0.1–1.1) mm	0.5 (0.2–0.8) mm	p = 0.005
Obs 2	1.3 (0.9–1.7) mm	0.6 (0.2–1.0) mm	p = 0.010
Obs 3	1.1 (0.6–1.6) mm	0.6 (0.4–0.8) mm	p = 0.020
Average	1.1 mm	0.6 mm	p = 0.001

JSW = joint space width; Obs = observer.

As in Table 1, a Bonferroni correction factor of 2 is considered in relation to the two outcome measure, implying statistical significance in the measured difference for p < 0.025.
