Descriptive statistics (Table 1)
We analyzed a total of 382 hospitalizations with the diagnosis of WAS.
114 had undergone HCT and 269 had not undergone HCT. Overall mean age of
admission was 5 years, with admissions in transplant arm having a mean
age of 3.6 years compared to 5.63 years for non-transplant arm. When
subcategorized for age (Figure 1) , most admissions were in the
0-5 year age in both groups, however there were more admissions in the
non-transplant arm after 6 years of age compared to transplant arm (p =
0.0612). There were 7 female patients in the non-transplant arm, the
rest were all male. There were more African Americans(18.3%) in the
non- transplant arm compared to transplant arm (6.8%). 50% patients
overall had Medicaid with equal distribution in both arms, the rest had
either private insurance or not reported (p = 0.395).
