Abbreviation: IQR, interquartile range.
The P value represents statistical testing based on Pearson’s chi-squared statistic for comparison of proportions.
The P value represents statistical testing for nonparametric distributions (Kruskal-Wallis or Wilcox rank sum depending on number of groups).
“Neither,” “Other,” and “Unknown” categories excluded for statistical testing.
“Unknown” designates that the field was completed but designed as “unknown” (in contrast from missing data [aka incomplete] fields).
“Diverse” refers to a combined group of “black” and “Hispanic” subjects.
“Neither” in these categories designates that the subject did not fit into the racial/ethnic category of Hispanic or black and, therefore, could not be classified by this metric.
