I don't know how this got ethics approval. Doing a trial in 600 people without a placebo or randomisation when you are using a potentially harmful treatment like transfusion is ridiculous. Of course, they aren't interested in proving whether it actually works. They will report that patients experienced subjective benefits and then engineer some surrogate blood biomarker of youth that 'improves' after transfusion. Then they will sell a transfusion product for at least the next 10-20 years it will take a proper trial to be conducted by someone else.
