  1. Mean difference in RSV between the period of interest (4 weeks surrounding WSD) and the control period (remaining weeks of the corresponding year) provided with the 95% confidence interval and P value
  2. P values are based on the two-tailed t test for computing the statistical significance. P < 0.05 was considered significant
