WebRegarding propensity score weighting (IPTW) when doing Cox proportional hazard modeling of time-to-event survival data: I have prospective registry data where we're interested in looking at treatment effect of a medication that in most cases the patients were already taking at baseline. I'm therefore not sure how to best analyze the data. IPTW uses the propensity score to balance baseline patient characteristics in the exposed (i.e. those who received treatment) and unexposed groups by weighting each individual by the inverse probability of receiving his/her actual treatment [21]. Weights are calculated for each individual as 1/propensityscore … See more We will illustrate the use of IPTW using a hypothetical example from nephrology. In this example we will use observational European Renal Association–European Dialysis and Transplant Association Registry data to … See more Treatment effects obtained using IPTW may be interpreted as causal under the following assumptions: exchangeability, no misspecification of … See more The propensity score was first defined by Rosenbaum and Rubin in 1983 as ‘the conditional probability of assignment to a particular treatment given a vector of observed covariates’ … See more In our example, we start by calculating the propensity score using logistic regression as the probability of being treated with EHD versus CHD.
