Three-way plots of relationships between SaO2 (y axis), ferritin/iron (x axis), and haematinic index (z axis). The most hypoxaemic patients are at the bottom of each graph, and patients with the lowest ferritin/iron levels to the left. The z axis effectively provides a 3 dimensional plot in which contours range from blue (lowest value of modelled haematinic variable) to red (highest values).
