What statistical bias is a key hurdle RWE statisticians must master methods to account for due to non-randomized assignment?

Answer

Confounding bias

Because RWE involves observational data without randomized assignment of treatment, a primary statistical challenge is mastering methods, such as causal inference techniques, to account for confounding bias, ensuring outcomes are attributable only to the intervention.
