  1. We tested five predictors using a linear regression between a response variable (Ne of each variant) and one variable or predictor (explanatory variables). The values in the table show the adjusted R-squared and (p-value). *: statistically significant. NA means that the variable was not recorded for all period of time that a particular variant circulated.
