  1. Differences in forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and the ratio of both parameters (FEV1/FVC) between asbestos exposed non-smokers and smokers without radiological evidence of asbestosis. Estimates expressed as percent predicted together with standard deviation (SD) and I2 as a measure of heterogeneity, n = number of subjects included in each subgroup.
