Incident Radiographic Vfx Versus Clinically Diagnosed Vfx

(A) Proportion of incident radiographic vfx also diagnosed as incident clinical vfx
Category of radiographic vfx	n	% (95% CI) with clinical vfx at ±1 vertebral level	% (95% CI) with clinical vfx at same vertebral level
Any (SQ grade change ≥1)	237	13.5 (9.4–18.5)	12.2 (8.3–17.1)
SQ grade change=1	84	8.3 (3.4–16.42)	8.3 (3.4–16.4)
SQ grade change≥2	153	16.3 (10.9–23.2)	14.4 (9.2–21.0)

(B) Proportion of incident clinical vfx also identified as incident radiographic vfx
Category of clinical vfx	n	% (95% CI) with radiographic vfx at ±1 vertebral level	% (95% CI) with radiographic vfx at same vertebral level
Any (SQ grade change ≥1)	37	86.5 (71.2–95.5)	78.4 (61.8–90.2)
SQ grade change=1	6	33.3 (4.3–77.7)	33.3 (4.3–77.7)
SQ grade change≥2	31	96.8 (83.3–99.9)	87.1 (70.2–96.4)

vfx=vertebral fracture; SQ=semiquantitative.
