Here are some other examples. We’ve reformatted the language and tables to make them easier to read, but they’re also from real studies.
See if you can find the error in this paragraph:
Hint: how old were the participants in this study
What’s wrong in this table?
Hint: compare the age mean with the age range of the people in the two treatment groups.
This table has a lot of data, but see if you can find the mistake.
Hint: how many patients in the fish oil group were on atenolol, captopril, or aspirin? How about the infarction site locations?
Sometimes study errors aren’t as obvious as the examples above. You’ll also see data in tables that don’t match the text or the figures.
