Table 2.

Performance of different entities at predicting the ground truth.

	Extracted from (%)	Mean absolute percentage error (%)	Median absolute percentage error (%)	Extracted entity within 10% from ground truth (%)	Extracted entity within 1% from ground truth (%)	Extracted entity equal to ground truth (%)
Randomized total	42.0	2.4	0.0	96.8	95.2	95.2
Analysis total	12.7	3.1	1.3	94.7	47.4	26.3
Completion total	20.0	9.5	6.2	70.0	20.0	10.0
General total	65.3	19.0	0.0	85.7	74.5	70.4
Arms	74.0	11.1	0.0	82.9	71.2	66.7
Arm events	39.3	61.7	7.0	50.8	27.1	20.3

The “Extracted from” column indicates the percentage of trials in which the respective entity was found. The remaining columns indicate the accuracy of the respective entity in predicting the ground truth, ie, how many people were randomized.
