3. Figure 2
Probabilty of developing CH after HSCT. (A) The probability of developing CH in the 68 study patients was 61.5% ± 9.1% at 25 years after HSCT. (B) Based on total cranial radiation dose, the probability was 0% in the patients who did not receive irradiation to the head before and/or during the conditioning treatment for HSCT, 62.0% ± 10.1% in those with a total cranial radiation dose of 6 to 12 Gy, and 100% in those with a total dose of 18 to 36 Gy. These differences are highly significant (P < .001).

Total CH scores according to total cranial radiation dose before and/or during conditioning treatment for HSCT. Total CH scores between 0 Gy and 6-12 Gy, between 0 Gy and Gy, and between 6-12 Gy and Gy were statistically significantly different. ∗P < .001, Mann-Whitney U test.
