Ever and cumulative occupational exposure and lung function decline in longitudinal population-based studies: a systematic review and meta-analysis

<p>Epidemiological studies suggest that some</p> <p>occupational exposures are associated with</p> <p>the decline in forced expiratory volume in</p> <p>1 s (FEV1) and forced vital capacity (FVC) or</p> <p>FEV1/FVC. However, the findings from general</p> <p>population-based studies are inconclusive and</p> <p>not systematically synthesised.</p>
