Study on the Relationship Between the Number of Adverse Drug Reactions of Essential Drugs and Visits: Based on Vector Autoregressive Model

Figures & data

Figure 1

Time-series analysis descriptive statistics of ADRs associated with basic drugs. Blue bar is ADR_CB, the ADRs caused by chemical drugs and biological preparations; red bar is ADR_TCM, the ADRs caused by Chinese traditional patent medicine; green bar is ADR_TOTAL, the all ADRs associated with basic drugs from 2011 to 2020.

Figure 2 Stationarity test of VAR system. All the unit roots (blue dot) were inside the unit circle, which means that the VAR sequence was stationary.

Figure 3 Response of EMADR_TOTAL to TV perturbation. Blue line is trace of impulse response values, between the red dotted lines are the response standard errors.

Figure 4 Response of EMADR_TOTAL to self-disturbance. Blue line is trace of impulse response values, between the red dotted lines are the response standard errors.

Figure 5

Variance decomposition of EMADR_TOTAL. Blue line is EMADR_TOTAL, the all ADRs induced by the basic drugs; red line is TV, the number of visitors from 2011 to 2020.
