Effect of DDAVP on TG. (A) Initial TG rate in PRP and GFPs reconstituted with FV–deficient plasma (FV-DP) at baseline and 4 hours after DDAVP (Wilcoxon signed rank test P < .001 for both comparisons; n = 38). (B) Relative increase of the initial TG rate (iTGR) in PRP and GFP/FV-DP at 4 hours compared with baseline (Wilcoxon signed rank test P < .001 for both comparisons; n = 38).
