Nice addition to the literature on this subject, and another reason not to lightly transfuse patients for fatigue or similar non-life threatening symptoms, except perhaps at the end of life..
Thrombosis has been convincingly shown to be associated with red cell transfusion in a randomized trial, as well as in some previous cohort studies. The same is true to some extent of cohort studies of platelet transfusion and plasma transfusion. Transfusions are pro-inflammatory and inflammation and thrombosis are closely linked both mechanistically and clinically.

Effect of erythropoietin and transfusion threshold on neurological recovery after traumatic brain injury: a randomized clinical trial.
“There was a higher incidence of thromboembolic events for the transfusion threshold of 10 g/dL (22/101 [21.8%] vs 8/99 [8.1%] for the threshold of 7 g/dL, odds ratio, 0.32 [95% CI, 0.12 to 0.79], P = .009).”
