Fig 2

Note: This figure shows the estimated distribution of placebos using the randomly generated "COVID" variable and "Con" variable on the impact of residents’ TCM literacy, taking into account the time of the outbreak of COVID-19 and whether there are confirmed cases of COVID-19 in the region, which is randomly assigned, so we get each estimate by executing our main model specification (with the addition of control variables), and we do this process 1000 times. where a and b represent the random "COVID" variable and "Con" respectively.
