Logistic Regression Analysis of the Impact of RVD at 5 Years
Postoperatively Factors
A generalization of the GBTM model was used to link different
baseline(before MVR) measures with FTR trajectory group membership while
control every potential confounding factors at baseline. Three different
generalizations of the GBTM model were fitted(table 2). Treating the
stable group as the reference, the increasing-slow group and the
increasing-fast group were all risk factors for RVD. odds ratio(OR)
value and 95% confidence interval(CI) were 33.77(95% CI, 15.97
-71.39), 180.92(95% CI, 61.64 -531.06); Treating the stable group as
the reference, the age- and sex-adjusted OR was 25.84(95% CI,
11.78-56.65) for the increasing-slow group and 139.94(95% CI,
45.47-430.68) for the increasing-fast group by logistic regression
model. After adjustment for every potential confounding factors(age,
sex, length of medical history, AF, PH, LAD, RATD, RALD, LVEDD, TRA),
compared with the stable group, the OR was 14.21(95% CI, 4.36-46.33)
for the increasing-slow group and 49.34(95% CI, 8.88-273.87) for the
increasing-fast group by logistic regression model.
