Fig. 5. Correlation matrix between SARS-CoV-2 case numbers and mobility data for Alpha and Delta variants in Cambodia.

Positive associations are represented by blue ellipsoids, while negative correlations are denoted by red ellipsoids. The intensity of color and ellipse size correspond to the strength of the correlation coefficients. Numbers in the center represent Pearson correlation coefficients. Statistical significance was determined using a P-value < 0.05, with non-significant correlations indicated by a cross symbol. Ne represents relative genetic diversity.
