From: Nonlinear relationship between visceral adiposity index and lung function: a population-based study
Association analysis between VAI level and lung function. Relationship of VAI levels with lung function FEV1% predicted (a) and FVC% predicted (b) in all the participants. Relationship of VAI levels with lung function FEV1% predicted (c), and FVC% predicted (d) in male participants. Relationship of VAI levels with lung function FEV1% predicted (e), and FVC% predicted (f) in female participants. Adjusted for age, economic income, education level, smoke exposure and other vital covariates including previous chronic bronchitis, COPD, hypertension, etc. FEV1 forced expiratory volume in 1 s, FVC forced vital capacity, VAI visceral adiposity index, COPD Chronic obstructive pulmonary disease
