Figure 3From: Early pregnancy peripheral blood gene expression and risk of preterm delivery: a nested case control study Heat map illustration of samples and selected differentially expressed genes. Selected genes (N = 209) differentially expressed (upregulated: shades of red and downregulated: shades of green) in whole blood associated with preterm delivery (rows) and participants (columns, cases = pink and controls = green) grouped according to level and nature of gene expression (genes) and similarity of expression profiles (participants) and subjected to hierarchical tree clustering.Back to article page
