Quantitative variables are presented as medians with interquartile ranges. The interquartile range represents the difference between the 75th and 25th percentiles. Categorical data is presented as percentages. Column values are compared by Mann-Whitney U test for quantitative variables and by Fisher’s exact test for categorical variables.
