  1. The correlation coefficient for MMRs and CS rates for each region were worked out by using the magnitude of both parameters of the regions. Overall correlation coefficient was calculated using the magnitude of the national MMR and CS rate and the numbers represent Pearson’s correlation coefficient (r)
