The three iron markers with best day 0 correlations to ferritin levels on day 42. Linear regression plots of log-transformed values of transferrin (a), transferrin saturation (b) and ferritin (c) on admission (day 0) vs log-transformed ferritin levels at steady-state (day 42). Individual data points (filled circle), and the associated linear regression line (with 95% confidence interval) are shown. The linear correlation coefficient (R2), its statistical significance, and the number of data points are indicated in the panel margin
