And it has on it, in each group, the number that got sick, the number that didn't get sick. And so we also can, from this, calculate the total number. So in group 1, we had a total of 120 people. In group 2, we had a total of 30 plus 110 is 140 people. And in the placebo group, the group that just got the sugar pill, we had a total of 120 people. And then we could also tabulate the total number of people that got sick. So that's 20 plus 30 is 50, plus 30 is 80.
