Notes: See Methods for explanation of surveillance system (SS) names. rho = Spearman rho estimate, possible range is -1 to + 1, ci = 95% confidence interval for rho. Font colours with respect to correlation: Green: 95% confidence interval ≥ 0.7; black = 95% confidence interval is entirely > 0 and but lower bound of CI is < 0.70; grey = 95% confidence interval crosses zero; orange 95% confidence interval < 0
