Figure 3
The relationship between \({\beta}_{{0}}\), \({\beta}_{{1}}\) and scientific productivity. (a) The scatter plot between \(\beta _{0}\) and scientific productivity. The point represents mean value and the error bar represents standard error of the mean. (b) The bar chart between \(\beta _{1}\) and scientific productivity. The bar represents mean value and the error bar represents standard error of the mean. (c) The estimated association between \(\beta _{0}\) and scientific productivity based on Table 3 model (5) using the “margins” function of STATA. The red cross mark represents the turning point. The error bar represents the 95% confidence interval
