  • Stable lung function (=) was defined as a deviation of <10% predicted in forced vital capacity, total lung capacity or diffusing capacity for carbon monoxide. Also changes in high-resolution CT during follow-up were categorised as stable (=), improved (↑) or worsened (↓). BAL: bronchoalveolar lavage; ND: not determined; X: present. #: follow-up time in months is shown in parentheses.
