Explanatory variables are reported as group tertile categories and as continuous values. Continuous values are reported per s.d. increase. All analyses are adjusted for age, sex, BMI, comorbidities and generalized OA (knee and hip OA severity). Additional adjustment of:
GS sum score,
KL sum score and
both.
Results with P-value <0.05 are shown in bold. TS: temporal summation; OR: odds ratio; KL: Kellgren Lawrence grading; GS: greyscale.
