Table 2 SI/NSI models predicting ROA incidence and progression

From: Does moderate or severe nonspecific knee injury affect radiographic osteoarthritis incidence and progression?

Variable OR (95% CI)
Dichotomous model
Knee NSI (ref. none)  
Any 1.36 (0.61, 3.02)
Knee SI (ref. none)  
Any 2.90 (1.04, 8.09)
Trichotomous model
Knee NSI (ref. none)  
Moderate 1.51 (0.61, 3.74)
Severe 0.90 (0.24, 3.40)
Knee SI (ref. none)  
Moderate 1.51 (0.33, 6.84)
Severe 4.35 (1.26, 15.02)
  1. ROA = radiographic OA.
  2. Models are adjusted for baseline age, sex, BMI, KL grade and years of follow-up.
