Fig. 1From: Inverse association of diabetes and dialysis with the severity of femoropopliteal lesions and chronic total occlusion: a cross-sectional study of 2056 casesAssociation of the clinical characteristics with lesion severity. Data are adjusted odds ratios and 95% confidence intervals for chronic total occlusion (a), lesion length ≥ 25 cm (b), and severe calcification (c), derived from the multivariate model in which all the variables listed in the figure were entered as the explanatory variables. Numbers for odds ratios are given in Additional file 1: Table S2Back to article page
