Table 2. Distribution of biochemical and physiological parameters in the total study population, as well as separated by group affiliation (model training sample N = 25/test sample N = 22) at baseline (columns 2–4) and follow-up (columns 6–8), given as median and bootstrapped 95% confidence interval of the median.

MPO was measured only at baseline. The p-values are derived from Mann-Whitney U tests assessing differences between the model training and the test sample.
