Categorical data, presented as counts and percentages, were compared using chi-square tests and/or Fisher exact test. The primary endpoint of MR or TR regression was analyzed using the Cox proportional hazard model, where variables with clinical relevance plus univariable P≤.05 were chosen for multivariable analyses. PCI was treated as a time-dependent variable in the multivariable model. Adjusted cumulative incidence for MR/TR regression and survival were presented using the Kaplan-Meier curves.

Effect of Telehealth Services on Mitral and Tricuspid Regurgitation Progression: Retrospective Study
Categorical data, presented as counts and percentages, were compared using chi-squared tests and Fisher exact test. The primary end point of MR or TR progression was analyzed using the Cox-proportional hazard model, where variables with clinical relevance plus univariate P
A total of 1081 patients (n=226 in the telehealth group and n=855 in the control group) were included in the study analyses. Patient baseline characteristics are shown in Table 1.

Between-group comparisons of discrete indicators at baseline (gender proportions, comorbidities, and medications) were analyzed using a chi-square test, while between-group comparisons of continuous indicators at baseline (age, average BP measurements per day, hemoglobin A1c (Hb A1c) levels, creatinine levels, and total cholesterol) were calculated using an ANOVA test.
We used paired t-tests to compare differences in BP values between patient groups.

The distribution of categorical variables was compared in the study group using the chi-squared test. There were no missing values in the basic variable collections in our cohort.
Kaplan-Meier curves were used to estimate survival rates of hospitalization for cardiovascular events, and a log-rank test was used to compare risks among the study groups. We further stratified the subjects according to the CHA2 DS2-VASc scores of 0-3 and 4-8.
