Table 4 Predictors of change in bone marrow lesion size

From: The clinical significance, natural history and predictors of bone marrow lesion change over eight years

  Univariable Multivariablea
Body mass index (kg/m2) 0.03 (0.00, 0.05) 0.03 (0.01, 0.05)
Strenuous activity (per unit change) 0.13 (0.03, 0.22) 0.14 (0.04, 0.23)
Current smoker (yes/no) 0.04 (-0.13, 0.20)
Ever smoker (yes/no) 0.06 (-0.20, 0.31)
Radiographic osteoarthritis (yes/no) 0.28 (-0.06, 0.61)
Light activity (per unit change) 0.02 (-0.10, 0.13)
Offspring status (yes/no) 0.13 (-0.11, 0.38)
Leg strength (kg) 0.00 (0.00, 0.00)
  1. Data presented as beta coefficient (95% confidence interval). Values are the change in bone marrow lesion size (cm2) per unit change in covariates. All factors are from visit two, except for radiographic osteoarthritis that was collected at visit one. Strenuous and light activity were assessed on a five-point scale: 1 = no days, 2 = 1 or 2 days, 3 = 3 to 5 days, 4 = 6 to 8 days and 5 = 9 days or more. Bold data indicate P <0.05. aAdjusted for age, sex, body mass index, and strenuous activity.
