Suppose a study found that people who drink coffee have a higher risk of heart disease.<br>The study looked at over 10,000 participants and found that those who drank more than 3 cups of coffee per day were more likely to develop heart disease compared to those who drank less than 1 cup per day.
Can we infer that "Drinking coffee is the only factor that contributes to heart disease."? Yes, no, or maybe?
