Fig. 3From: Associations between weight-adjusted waist index and bone mineral density: results of a nationwide surveyThe nonlinear associations between weight-adjusted waist index and bone mineral density. The solid line represents the smooth curve fit between variables. Blue bands represent the 95% of confidence interval from the fit.
