So there's a very, very small probability that we could have gotten this result if the null hypothesis was true. So we will reject it. And in general, most people have some type of a threshold here. If you have a p-value less than 5%, which means less than 1 in 20 shot, they'll say, you know what, I'm going to reject the null hypothesis. There's less than a 1 in 20 chance of getting that result. Here we got much less than 1 in 20. So this is a very strong indicator that the null hypothesis is incorrect and the drug definitely has some effect.
