Fig. 4

The Interaction Effect of NRCMS between H_rate and CUP1 in model 7. Note: 1. Figure 4 illustrates the moderating effect of the New Rural Cooperative Medical Scheme (NRCMS) enrollment rate on the relationship between inpatient admission rate (H_rate) and survival-related consumption expenditure (CUP1)。 2. The x-axis in Fig. 4 represents the inpatient admission rate (H_rate), while the y-axis shows the predicted values of survival-related consumption expenditure (CUP1). 3. The blue line in Fig. 4 represents the variation in survival-related consumption expenditure as the inpatient admission rate increases, for NRCMS enrollment rates of 2% and 100%, highlighting the moderating role of NRCMS enrollment rate in this relationship
