State-transition analysis Sensitivity GLMMs with nested random intercepts confirmed the Markov findings: the post-exchange phase was associated with reduced odds of incident bleeding (OR 0.14, 95% CI 0.029–0.67, p = 0.014) and showed a trend toward reduced bleeding persistence (OR 0.18, 95% CI 0.028–1.14, p = 0.069).
