Fig 1 shows the selection process of the index hospitalizations for TAVR from NRD 2017 to 2018, which are then stratified to those with and without a co-diagnosis of ESRD.

Overlap plot for propensity score.
Overlap plot for the estimated density of the propensity score distances among patients undergoing TAVR with versus without co-diagnosis of ESRD.

Fig 3.
Kaplan-Meier curves of all-cause and cardiovascular readmissions after TAVR in patients with and without ESRD.
Kaplan-Meier curve on the left shows the probability of being readmission-free for any cause in patients with and without ESRD over 90 days after discharge from the index hospitalization. Similarly, the Kaplan-Meier curve on the right shows the probability of being readmission-free for cardiovascular cause.
Fig 4.
Reasons for post-TAVR readmissions in patients with and without ESRD.
The pie graph on the left (Fig 4A) illustrates the percentage of different causes of 90-day readmissions in patients with ESRD. Each cause is color-coded according to the legend below the pie graph. Arrhythmia has been further divided into atrioventricular block, atrial fibrillation, and other conduction disorders. The same applies for the pie graph on the right (Fig 4B), but in patients without ESRD. Abbreviations: CV = cardiovascular; GI = gastrointestinal.
Fig 5.
Potential risk factors for 90-day readmission after TAVR in patients with ESRD.
Fig 5 shows the odds ratio of each potential risk factor associated with 90-day readmission from the multivariable logistic regression model. Odds ratio above 1 is predictive of 90-day readmission while that below 1 is protective for 90-day readmission. Each vertical line inside the blue box shows the odds ratio while the perpendicular horizontal lines show the corresponding 95% confidence interval. The size of the blue box is indirectly proportional to the size of the confidence interval.
