Table 2 Cross sectional associations between presence of hip pain and categories of hip effusion-synovitis

From: Quantification of hip effusion-synovitis and its cross-sectional and longitudinal associations with hip pain, MRI findings and early radiographic hip OA

Study factor Presence of hip pain Severity of hip pain
Categories of hip effusion-synovitis Adjusted PR (95%CI)a Ratio of means (95%CI)b
Presence of moderate/large hip effusion-synovitis 1.31 (0.98, 1.74) 0.81 (0.53, 1.08)
Presence of hip effusion-synovitis at two/three sites 1.42 (1.05, 1.93) 0.99 (0.70, 1.40)
  1. Independent variable: presence and severity of hip pain. Dependent variable: hip effusion-synovitis (moderate/large & multiple sites)
  2. The variable small or no hip effusion-synovitis includes participants with hip effusion-synovitis less than 0.77 cm2 and the variable moderate/large hip effusion includes participants with effusion-synovitis more than equal to 0.77 cm2
  3. aPR (95%CI) = prevalence ratios (95% confidence intervals) adjusted for age, sex, BMI, presence of hip BMLs, presence of cartilage defects and with clustering of observation on subjects at phase 2 and phase 3 taken into account
  4. bRatio of means (95% confidence intervals) adjusted for age, sex, BMI, presence of hip BMLs, presence of hip cartilage defects and with clustering of observation on subjects at phase 2 and phase 3 taken into account
