OR of hip fracture by quartiles of TNF-sR1 and TNF-sR2. Quartile 1 is reference strata; OR = 1. Linear trend: *, P < .05; **, P < .01. Error bars denote 95% CI. Data are adjusted for FRAX score, nutritional variables (intake of calcium, vitamin D, total energy, protein, multivitamin use), and factors impacting inflammation (NSAID use, arthritis, depression, body mass index, self-reported general health, comorbidity index, physical function, poor endurance/exhaustion, and physical activity).
