Relationship of CT-quantified emphysema, small airways disease and bronchial wall dimensions with physiological, inflammatory and infective measures in COPD

Table 6 Logistic regression predicting which variables contributed to patients walking over 350 m or desaturating during the 6MWT

	Odds ratio	95% Lower CI	95% upper CI	significance
6MWD > 350 m
FEV1%	1.049	1.019	1.079	0.001
Female	0.379	0.165	0.871	0.022
Desaturation > 5%
%LAA_<−950	1.101	1.059	1.143	< 0.001

44 subjects desaturated > 5% and 76 subjects did not
45 subjects walked over 350 m and 75 subjects did not
%LAA_<− 950, E/I MLD and PI10, FEV1% and demographics variables (age, gender, current smoking status, pack years and BMI) were combined into a regression model to predict each of the dependent variables. Only variables that made a significant difference to the model are included in the results
