Question 7

You read a study that compares two surgical procedures and their respective outcomes. Their data is derived from English-language journals. What effect does the fact that english-language only journals were used haveon this study?

A) It renders the results applicable to English-only regions
B) It has no bearing on the conclusions of this paper
