The number (N) of instances for each organ measurement is provided per machine. The Mann-Whitney U-test U score and (critical value) along with Z-score p values are provided; significance for Mann-Whitney U-test results that were determined to be normal was based on Z-score p values only, i.e., no critical value was provided
