Table 2.

The associations of combinations of MRI features that became worse with progression of radiographic JSN from baseline to 30-month follow-up. The percentages presented refer to the total of 528 tibiofemoral compartments included in the analysis.

MRI feature	Any progression of JSN		Adjusted OR** (95% confidence intervals)
MRI feature	Absence	Presence	Adjusted OR** (95% confidence intervals)
Number of features showing worsening*
No worsening of all 3 MRI features	366 (69.3%)	18 (3.4%)	1.0 (reference)
Worsening of 1 of the 3 MRI features	85 (16.1%)	27 (5.1%)	6.5 (3.4, 12.2) p<.0001
Worsening of 2 of the 3 MRI features	10 (1.9%)	11 (2.1%)	22.5 (8.8, 57.5) p<.0001
Worsening of all 3 MRI features	2 (0.4%)	9 (1.7%)	92.6 (18.7, 457.4) p<.0001
