So far we have discussed the use of IPTW to account for confounders present at baseline. In longitudinal studies, however, exposures, confounders and outcomes are measured repeatedly in patients over time and estimating the effect of a time-updated (cumulative) exposure on an outcome of interest requires … See more We will illustrate the use of IPTW using a hypothetical example from nephrology. In this example we will use observational European Renal … 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 … 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. We include in the … See more IPTW uses the propensity score to balance baseline patient characteristics in the exposed (i.e. those who received treatment) and unexposed groups by weighting … See more WebConvert P S P S to I P W I P W = A P S + 1−A 1−P S A P S + 1 − A 1 − P S Convert PS to IPW using the formula. We are using the formula for average treatment effect (ATE). It is possible to use alternative formulas, but we are using ATE formula for our illustration.
