Dahl R, Jadayel D, Alagappan VKT, Chen H, Banerji D. Int J Chron Obstruct Pulmon Dis. 2013;8:501–508.
On page 501, note that in the Results section of the Abstract, the sentence "Trough FEV1 at week 4 for QVA149 and IND+GLY was 1.46 L ± 0.02 and 1.46 L ± 0.18, respectively." should read "Trough FEV1 at week 4 for QVA149 and IND+GLY was 1.5 L ± 0.02."
On page 505, note that the sentence "The least squares mean ± standard error (LSM ± SE) trough FEV1 at week 4 for QVA149 and for the free-dose combination of IND+GLY was 1.5 L ± 0.02 and 1.5 L ± 0.18, respectively (Figure 3)." should read "The least squares mean ± standard error (LSM ± SE) trough FEV1 at week 4 for QVA149 and for the free-dose combination of IND+GLY was 1.5 L ± 0.02 (Figure 3)."
On page 505, note that the confidence interval for Figure 3 was incorrect, and the confidence intervals and y-axis for Figure 4 were also incorrect. The full and correct figures are given here.
