40 seconds (interquartile range (IQR): 12761) for COL/EPI, and 113 seconds (IQR: 108118) for COL/ADP. Correlations between BS and phenotypic laboratory test outcomes had been not discovered to be statistically substantial for either in the performed tests, as follows: platelet count ( = 0.09, 95 confidence interval (CI): -0.32 to 0.47, P = 0.671), PT ( = -0.12, 95 CI: -0.49 to 0.29, P = 0.559), aPTT ( = -0.06, 95 CI: -0.44 to 0.35, P = 0.792), vWF:GPIbM ( = -0.35, 95 CI: -0.65 to 0.06, P = 0.089), vWF:Ag ( = -0.18, 95 CI: -0.54 to 0.23, P = 0.379), FVIII:C ( = 0.07, 95 CI: -0.33 to 0.45, P = 0.735), and vWF:CBA ( = -0.21, 95 CI: -0.56 to 0.20, P = 0.318).DiscussionThe present study combined the evaluation of clinical symptoms according to BS calculation with laboratory analyses such as phenotypic laboratory assays and NGS molecular diagnostics in a cohort of paediatric individuals with previously diagnosed vWD. This expanded diagnostic method yielded numerous useful findings.
