Table 3.

The mean and standard deviation of the area under the curve of the receiver operating characteristic curve was recorded after each of the 100 different XGBoost classification models. Each run used a different set of people who did not have a severe reaction to COVID-19. The mean AUC for all three datasets was well described by a normal distribution, as confirmed by a Shapiro normality test

	Mean AUC	SD AUC
1930 data	0.515	0.017
1940 data	0.516	0.019
1950 data	0.511	0.030
