The blue line should be annotated as the shape of the exposure-response association at low temperature, and the red line should be at high temperature. Also, due to errors in the result reading, the exposure-response shape under low temperature in figure 4(d) has not been plotted correctly for this article, which has been revised. Although there are slight changes in the shape of the curve in figure 4(d), the overall conclusions of the modification effect are not affected, and the statements of the paper remain.
The figures with the correct legend and shape are shown below.
