Kaplan-Meier curve of all-cause (A) and CV mortality (B).
These parameters were compared between four groups according to serum B2M. Abbreviations: CV, cardiovascular; B2M, β2 microglobulin.
Fig 3.
HRs for all-cause mortality derived from univariate [A] and multivariate analysis [B].
Lines represent HRs and 95% CIs based on restricted cubic splines for serum B2M levels with five knots at the 5th, 27.5th, 50th, 72.5th, and 95th percentiles. Abbreviations: HR, hazard ratio.
