Table 1 Baseline participant characteristics according to the presence of any BML being present1

From: Bone marrow lesions can be subtyped into groups with different clinical outcomes using two magnetic resonance imaging (MRI) sequences

  No BML BML on T2 only BML on T1 and T2 p value2
N = 258 N = 9 N = 29
Age (years) 57.7 (5.2) 59.8 (7.6) 59.9 (6.0) 0.06
Gender, n (%) female 159 (62) 7 (78) 20 (69) 0.483
BMI (kgm−2) 25.7 (4.1) 27.0 (4.0) 27.5 (5.5) 0.09
Baseline tibial cartilage volume (mm3)
 Medial 1695 (532) 1609 (382) 1807 (554) 0.49
 Lateral 2026 (648) 1994 (724) 2012 (610) 0.98
  1. Results expressed as mean (standard deviation) or number (%)
  2. BML bone marrow lesion, BMI body mass index
  3. 1One participant had a BML present only on T1-weighted sequences, and was not included
  4. 2 p value expressed as F test – pairwise comparisons among the unadjusted means
  5. 3Chi-square test
