Figure 2From: Surfactant protein A genetic variants associate with severe respiratory insufficiency in pandemic influenza A virus infectionLinkage disequilibrium (D’) among genetic polymorphisms of surfactant proteins in general Spanish population ( N = 687). LD plots for pair wise Dʹ between markers and Dʹ values are indicated in percentages within squares in the LD plot. Strong LD is indicated by dark gray/red, whereas light gray/pink and white indicate uninformative and low confidence values, respectively.Back to article page
