a–b Scatter plots showing the variation in lncRNA (a) and mRNA (b) expression between the vocal cord leukoplakia and normal vocal cord tissue arrays. The values of the X and Y axes in the scatter plot are averaged normalized values in each group (log2-scaled). The lncRNAs above the top green line and below the bottom green line are those with a > 3-fold change in expression between the two tissues
