Correction to: BMC Pulm Med (2021) 21:136 https://doi.org/10.1186/s12890-021-01509-3
Following publication of the original article, the authors flagged that a calculation error had been made in the calculation of quality of life scores in Table 5 (specifically, of SF-12).
Table 5
QoL assessment at three months
Normal value | Overall (39) | CT improving at 3 mo (31) | CT not improving at 3 mo (8) | P value | |
|---|---|---|---|---|---|
St George symptoms (median and 25th–75th) | 12 (9–15) | 16.3 (10.4–29.8) | 16.3 (10.4–29.8) | 20.5 (6.5–31.7) | 0.84 |

St George impact (median and 25th–75th) | 2 (1–3) | 4 (0–11.5) | 2 (0–8.2) | 12.2 (0–414) | 0.13 |

As before, 31 patients (79.5%) presented an abnormal total score in the St. George’s Respiratory Questionnaire. Concerning SF-12, the authors have split it in its physical and mental components and corrected a critical error in calculating the scores. At 3 months, 19 (48.7%) and 12 (30.8%) patients had an abnormal SF-12 score in physical and mental components, respectively. Still, the authors have not found any significant difference in SF-12 scores among those who showed radiological improvement at 3 months. The other findings related to quality-of-life outcomes remained similarly unchanged. Finally, the authors have updated the normal values choosing those widely accepted in literature, removed the speculative analysis comparing overall results with the aforementioned normal values and, since the distribution was not normal, chosen to describe the data as median and interquartile range.
The authors thank you for reading this correction and apologize for any inconvenience caused.
