Fig. 5From: Longitudinal association between adiposity changes and lung function deteriorationMultiple linear mixed regression analysis for lung function decline according to adiposity changes in women. Lung function declines were compared between the WHR-decreased and -increased groups in fat-loss and fat-gain group, respectively. Decline of a FVC in the fat-loss group, b FVC in the fat-gain group, c FEV1 in the fat-loss group, d FEV1 in the fat-gain group, e FEV1/FVC in the fat-loss group, and f FEV1/FVC in the fat-gain group. Individual changes in FMI during follow-up were calculated with linear regression analysis. Participants with a slope of FMI change < 0 were classified under the fat-loss group, and those with a slope > 0 were classified under the fat-gain group. No participant had a zero-degree slope of FMI change throughout the study period. Individual changes in WHR during follow-up were calculated with linear regression analysis. Participants with a lower 30% of WHR change were designated to WHR-decreased group, and those with an upper 30% of WHR change were to WHR-increased group. WHR-stable group comprised the median 40% of participants, which included a zero-degree slope. Analysis was conducted in non-smoking women; age, height, residential area, follow-up duration, initial lung function, initial FMI, and initial WHR were adjusted. The gray shadow and numbers in parentheses represent 95% confidence intervals. *P-value between WHR-decreased and -increased group.
