  1. |r| > 0.5 represents a large degree of correlation, 0.3 < |r| < 0.5 represents a moderate degree of correlation and 0.1 < |r| < 0.3 represents a small degree of correlation; |r| < 0.1 represents a lack of correlation (upper panel). Only PBMC subpopulations are shown for which P was < 0.05. A low P value indicates that the observed correlation coefficient is due to a statistically significant relation between the two variables.
