See caption of Figure 3 for interpretation of boxplots. Not shown are cases where the new participant ratio is infinite (7 cases out of 10000, 5 [71%] of which were in the out-of-date group) or where the new participant ratio < 1/100 (1361 cases out of 10000, 6 [0.4%] of which were in the out-of-date group).
