Change in calcium absorption with increasing phytate-P intake (PP) at three different levels of exogenous phytase intake (ExPhyt), to illustrate the interaction between PP and ExPhyt identified in the final linear mixed effects regression model for calcium absorption. At higher ExPhyt (Inline graphic: ExPhyt set to its mean+sd from the data set), calcium absorption increases with increasing PP. Lower ExPhyt (Inline graphic: ExPhyt set to its mean value from the data set) and no additional ExPhyt (Inline graphic) lead to an overall decrease in calcium absorption with increasing PP. The remaining variables (total calcium intake and non-phytate-P intake) were fixed and set to their mean values from the data set. BW, body weight.
