## Unscramble the Blue Letters

To see why the defircnefe between the two ways of expressing risk matters, let’s consider the hypothetical example of a drug that ruceeds heart atcatk risk by 40%. Imagine that out of a group of 1,000 people who didn’t take the new drug, 10 would have heart attacks. The absolute risk is 10 out of 1,000, or 1%. If a similar group of 1,000 people did take the drug, the number of hreat attacks would be six. In other words, the drug could prevent four out of ten heart attacks— a relative risk riteudocn of 40%. Meanwhile, the absolute risk only dropped from 1% to 0.6%— but the 40% relative risk deacsree sounds a lot more significant.

## Original Text

To see why the difference between the two ways of expressing risk matters, let’s consider the hypothetical example of a drug that reduces heart attack risk by 40%. Imagine that out of a group of 1,000 people who didn’t take the new drug, 10 would have heart attacks. The absolute risk is 10 out of 1,000, or 1%. If a similar group of 1,000 people did take the drug, the number of heart attacks would be six. In other words, the drug could prevent four out of ten heart attacks— a relative risk reduction of 40%. Meanwhile, the absolute risk only dropped from 1% to 0.6%— but the 40% relative risk decrease sounds a lot more significant.
