Figure 4. Distribution of %EC values in preload studies (n = 253) according to preload weight, preload energy content, and preload energy density.

The Spearman's rho coefficient is indicated. Y-axis values are to be interpreted as for Figure 2, in reference to the 100%EC line (dotted line). * Significant correlation at the p < 0.05 level; ** p < 0.01.
