WebObjectives: Inverse probability of treatment weighting (IPTW) has been used in observational studies to reduce selection bias. For estimates of the main effects to be obtained, a pseudo data set is created by weighting each subject by IPTW and analyzed with conventional regression models.

WebSep 3, 2024 · Because the baseline characters of two group were different, IPTW were used to balance the two groups, and it has been done in R. "cmprsk" package in R were used to get cumulative incidence curves (CIFs) for competing risk. I know how to get a non-weigted CIF in the crude cohort, however, I don't know how to creat a weighted CIF in IPTW cohort. WebAug 26, 2024 · Some simulation studies have demonstrated that depending on the setting, propensity score–based methods such as IPTW perform no better than multivariable regression, and others have cautioned against the use of IPTW in studies with sample sizes of <150 due to underestimation of the variance (i.e. standard error, confidence interval …
