Figure 1From: Discordant effect of body mass index on bone mineral density and speed of soundSpearman rank order correlation coefficient of body mass index (BMI) and bone mineral density (BMD) at the femoral neck (a) and speed of sound (SOS) at the radius (b). Lean patient marked as filled squares and overweight women in open squares. The correlation between BMI and femoral neck BMD is statistically significant (R = 0.68, P < 0.0001).Back to article page
