Levels of Evidence in the Clinical Sports Medicine Literature: Are We Getting Better Over Time?

Conclusion: There has been a statistically significant increase in the percentage of level 1 and 2 studies published in the sports medicine literature over the past 15 years, particularly in JBJS-A and AJSM. The largest increase was seen in diagnostic studies, while therapeutic and prognostic studies demonstrated modest improvement. The emphasis on increasing levels of evidence to guide treatment decisions for sports medicine patients may be taking effect.
