View larger version (18K): [in a new window]   Fig. 1. Relationship of fan-beam dual energy X ray absorptiometry (DXA) measurements to scale weight and chemical analysis. Open circles represent 14 larger piglets, and asterisks represent five smaller piglets. Regression line and r2 value represent the relationship for all 19 piglets.

Scatter plot of 22 piglets with measured versus predicted fan-beam dual energy X ray absorptiometry (DXA) measurements for total weight, bone area, bone mineral content, bone mineral density, lean mass and fat mass. Lines indicated mean regression and 95% confidence interval for the mean. Number in parentheses = adjusted r2 and standard error of estimate, respectively.
