1.3 Statistical method
SPSS 25.0 software was used for statistical analysis. Demographic characteristics were described as classified variables. According to the score, the high-score group and low-score group were divided. With the score as dependent variable and the demographic characteristic and medical institution type as independent variables, single variate analysis was performed first by Chi-square test. Factors with P<0.05 were selected for unconditioned multivariate logistic regression analysis (α ingress = 0.05, α deletion = 0.10) to analyze the influences of different demographic characteristics and medical institution type on scores.
