Statistical analysis
Data were analyzed using the JMP software (SAS Institute, Cary, NC,
USA). Continuous variables were compared using the independent t-test or
the Mann–Whitney U test, while categorical data were analyzed
using the chi-squared test. A binary logistic regression approach was
adopted to evaluate the independent predictive factors and to create an
odds risk of the occurrence of AHRE. A receiver-operating characteristic
(ROC) curve was used to analyze the diagnostic accuracy, sensibility,
specificity, and predictive value of PWD for new-onset AHRE. For all
comparisons, p <0.05 was considered to be statistically
significant.
