Table 2. DSA Characteristics of DSAPosAMRNeg and DSAPosAMRPos Populations.
Categorical variables were expressed as a percentage and a number, while quantitative variables were expressed either as median with 25–75 interquartile range (IQR) unless specify as § for mean±SD. Fisher or Chi-square tests were used for categorical variables. Mann-Whitney test was used for continuous variables.
