Correction: Randomized trial of physical activity on quality of life and lung cancer biomarkers in patients with advanced stage lung cancer: a pilot study

Abstract

Following publication of the original article [1], the authors report an error. Table 3 (Baseline Patient-Reported Outcomes by Study Group) incorrectly references standard error (SE). In fact, the parenthetical numbers represent standard deviation (SD). Standard error (SE) is correctly referenced in Table 4 (Overall Patient-Reported Outcomes by Study Group (Mixed Effects Model)). The findings and Conclusions of the paper are unchanged. The authors apologize for the oversight.
