The association between organizational characteristics, socioeconomic and demographic factors, health status and health system capacity and the growth in the health policy competency scope of regional organizations. Poisson pseudo-likelihood regression with multiple levels of fixed effects was used for analysis. The left column shows the estimated associations of key factors with changes in the health policy scope of regional organizations by the two-way fixed effects regression model. The middle column shows the estimated associations of the time-fixed effect regression model. The right column represents the estimated associations of the individual fixed effect regression model. Red indicates the association is not significant, and green indicates the association is significant at a 95% CI with a Bonferroni correction. CV, coefficient of variation
