## Figure 1.
Illustration of the different distributions of a covariate (X) in two non-randomized
samples (A & B). The propensity score method (PS) aims at re-creating the conditions of a pseudorandomization,
while the inverse probability weighting (IPW) approach aims at re-creating a pseudopopulation
where patients A and B are exchangeable. Both methods aim at obtaining a similar distribution
of the covariate X in the two groups.
