Abstract

Boutou AK, Raste Y, Demeyer H, et al. Int J Chron Obstruct Pulmon Dis. 2019;14:1979–1992. On page 1985, the Table 3 title reads: Estimated coefficients and corresponding confidence intervals of GLM regressors, calculated for each physical activity parameter recorded by Dynaport MiniMod monitor This Table 3 title should read: Estimated coefficients and corresponding confidence intervals of GLM regressors, calculated for each physical activity parameter recorded by Actigraph GT3X monitor. On page 1990, the second sentence in the left column reads: Likewise, adverse street characteristics, such as lack of sidewalks and streetlights are negatively associated with PA among adults.35,34 The sentence with the correct citations should read: Likewise, adverse street characteristics, such as lack of sidewalks and streetlights are negatively associated with PA among adults.34–36 On page 1990, the third sentence in the second paragraph in the left column reads: These characteristics mirror the findings in pulmonary rehabilitation studies where those patients who drop out have worse exercise capacity, are more breathless, have poorer health-related quality of life and weaker quadriceps strength.37,36 The sentence with the correct citations should read: These characteristics mirror the findings in pulmonary rehabilitation studies where those patients who drop out have worse exercise capacity, are more breathless, have poorer health-related quality of life and weaker quadriceps strength.37,38 On page 1990, the second to last sentence in the first paragraph in the right column reads: In the single-center study of Watchki et al, the dropout rate was 20%,9 which is lower than the present study (33%), but still a significant number, while in similar studies conducted among COPD patients who undergo pulmonary rehabilitation, dropout rates may be as high as 30–40%.37,36 The sentence with the correct citations should read: In the single-center study of Watchki et al, the dropout rate was 20%,9 which is lower than the present study (33%), but still a significant number, while in similar studies conducted among COPD patients who undergo pulmonary rehabilitation, dropout rates may be as high as 30–40%.37,38 Following a review of our paper post-publication, we found the incorrect in-text reference citations. The correct in-text reference citations are shown in this corrigendum. These corrections have no impact to the findings of the study. The authors apologize for this error.
