Kaplan-Meier-analysis indicating the improvement of the clinical symptoms during the observation period of 12 months. (A) Improvement of clinical activity as assessed by the reduction to score 1 or 0. Clinical activity has decreased in 74% of the non-smokers and in 53% of the smokers to score 1 or 0 after 12 months (p<0.05). (B) Improvement of motility as assessed by a reduction from score 3 or 2 to score 1–0. Motility has improved in 60% of the non-smokers and in 24% of the smokers after 12 months (p<0.017). (C) Improvement of proptosis defined as reduction of more than 2 mm. Proptosis has decreased more than 2 mm in 5% of the non-smokers and in 9% of the smokers after 12 months. The difference was not significant.
