Abbreviations: HGS, hand grip strength; FEV1% pred, forced expiratory volume in 1 second, percentage of predicted value; B, beta coefficient from multiple linear regression models with HGS as a dependent variable, adjusted for age, height, heart disease, FEV1% pred, and in the total study population also adjusted for sex; CI, confidence interval.
