Hypothesis

What is the relationship between the global burden of disease and randomized clinical trials conducted in Latin America?

Conclusion

There is a poor correlation between the burden of disease and the publication of randomized clinical trials in Latin America.

Supporting Evidence

  • Non-communicable diseases represent 48% of the burden of disease but only 14% of reported trials.
  • No trials addressed injuries, despite them contributing 18% to the burden of disease.
  • The majority of trials focused on communicable diseases, particularly traveler’s diarrhea.

Takeaway

This study found that many important health issues in Latin America are not being studied in clinical trials, even though they cause a lot of problems for people.

Methodology

The study analyzed randomized clinical trials published in five leading medical journals from 1990 to 2006 that were conducted in Latin America.

Potential Biases

There may be bias in publication favoring certain types of diseases over others.

Limitations

The study only included trials published in five leading medical journals, potentially missing other relevant studies.

Participant Demographics

Trials were conducted in various Latin American countries, including Brazil, Mexico, and Argentina.
