Researchers are testing a medication to prevent migraines. In a randomized trial, 60,00060,000 subjects were divided into two groups. 30,10030,100 received the medication, and 1212 of them experienced migraines. The other 29,90029,900 received a placebo, and 4747 of them experienced migraines. The pp-value for the difference in migraine rates is less than 0.0010.001. What should be concluded about the medication's effectiveness?

There is strong evidence that the medication reduces migraine occurrence

There is strong evidence that the medication increases migraine risk

There is no evidence that the medication has any effect

The results are inconclusive about the medication's effect
