Association of handgrip strength with acute respiratory events

	Any Event at Baseline (Rate Ratio)	Any Event during Follow-Up (Rate Ratio)	Any Severe Event during Follow-Up (Rate Ratio)
Handgrip strength (per 1 kg decrement)	1.05 (1.01–1.08)	1.04 (1.01–1.07)	1.06 (1.01–1.12)
Lung function
FEV1% predicted	0.99 (0.98–1.00)	0.99 (0.98–1.01)	0.99 (0.98–1.01)
Chronic bronchitis	1.33 (0.80–2.20)	0.82 (0.48–1.40)	0.58 (0.22–1.50)
Exacerbations at baseline	N/A	1.18 (1.00–1.38)	1.29 (1.01–1.65)

Definition of abbreviation: N/A = not applicable.

All entries represent rate ratios and 95% confidence intervals. All models included all variables presented in the table and were also adjusted for age, sex, body mass index, race, pack-years smoked, currently smoking, emphysema, and airway metrics. Models during follow-up were also adjusted for history of acute events at enrollment.
