Survival functions for different spirometry parameters and disability pension. The total number of study subjects is 3386 and the number of the participants in each quartile is 846 or 847. Each quartile’s range of the spirometry parameter is in paracenteses. All models are adjusted with age, gender, education level, body mass index, co-morbidities, smoking and cotinine. * In the survival functions of FEV1/FVC and disability pension highest and 3rd quartile are equal. FEV1= forced expiratory volume in one second, FVC= forced ventilation capacity
