Relative gene expression and correlation between gene expression levels. A Hierarchical clustering heatmap of relative expression levels of six Plasmodium falciparum ligand genes (rows) between clinical isolates (columns). White to light red colour signifies lower expression while brown colour indicates higher expression. B Correlation between gene expression levels; numbers out of the brackets in square boxes represent the correlation coefficients while those in brackets represent the P values. Significant P values are indicated in red
