The genetics of acute lung injury: looking back and pointing the way forward.

Abstract

Individual genetic factors have long been suspected of playing a major role in susceptibility to acute lung injury and acute respiratory distress syndrome. Flores and colleagues evaluate the quality of published studies testing the relationships between variation in candidate genes and susceptibility to lung injury syndromes or worsened outcome in patients with these conditions. Their results demonstrate that while important advances have been made in this area, attention should be paid to improving the methodology of future studies in order to minimize the chances of publishing false-positive results.
