  1. Abbreviations: IRR Incidence rate ratio, β Regression coefficient of (group:post), SE Standard error, EQ-5D EuroQol-5D, EQ-VAS EuroQol-visual analog scale
  2. *p < 0.05, statistically significant
  3. 1Main effect analysis: Eight covariates were adjusted
  4. 2Sensitivity analysis: Among eight covariates, only those with significant differences between the two groups in the pre-survey, which was ‘family type’, was adjusted
  5. 3The IRR is an exponentially multiplied value of regression coefficients. Among them, this represents\({e}^{regression coefficient of group:time}\)
  6. 4The β is a regression coefficient. Among them, this represents the coefficient of interaction term (group:time) in regression analysis
  7. 5This column presents p-values of difference-in differences model with regression analysis. The number of outpatient visits, absences, lateness/early leaves, and infectious symptoms were based on the zero-inflated negative binomial regression analysis; the ED-5D and ED-VAS were based on the tobit regression analysis
