Table 3 Relationship between Presence of Complication to Post-TAVR Length of Stay, with Unadjusted and Adjusted Analyses. Hazard ratios with 95% confidence intervals for post-TAVR LOS according to presence of different complications. Includes unadjusted analysis as well as multivariable adjustment for baseline and procedural characteristics
