Correction to: BMC Pulm Med (2020) 20:27

Following publication of the original article [1], the authors have flagged that there is an error in Fig. 3.

Namely, asterisks indicating significant difference are missing in the figure.

Please see the correct version of Fig. 3 in this correction article.

The authors apologize for any inconvenience caused.

Fig. 3
figure1

Relative change in SP-A, SP-D, and KL-6 levels in the initial 3 and 6 months in the stable and progression groups. Changes in SP-A at 3 and 6 months, SP-D at 6 months, and KL-6 at 3 and 6 months were significantly smaller in the stable group than the progression group (*p < 0.05). Data were analyzed by Mann-Whitney U test. Horizontal line indicates median concentration. The upper and lower limits of the box indicate the inter-quartile range
