SPSS 26.0 software was used for two-person data entry and analysis. Descriptive statistics were used to describe the means, standard deviations, expert positivity coefficients, expert authority coefficients, and the degree of expert opinion concentration of general information of experts. The expert positivity coefficient was expressed as the return rate of the questionnaire. Expert authority coefficient (Cr) = expert judgment coefficient (Ca) + expert familiarity (Cs)/2. The degree of expert opinion concentration was expressed as the mean of importance assignment. The degree of expert opinion coordination was expressed as coefficient of variation (CV) and Kendall’s coordination coefficient (Kendall’s W), and non-parametric tests were used to calculate the degree of expert opinion coordination, etc. Differences were considered statistically significant at P < 0.05.
