The increase in PTX3 protein levels was very similar in patients who either did or did not subsequently develop GvHD [median RC = 3.24 (range = −0.>51; 30.40) vs 3.20 (range = −0.71; 27.88), p = 0.91, respectively], indicating that the increase in PTX3 levels at day 0 was not related to a higher risk of GvHD occurrence within day +100 (Figure S1). The gene discussed is PTX3; the disease is graft versus host disease.
