FIG. 6.

Analysis of variance showed that there was significant postoperative improvement in both the Delis–Kaplan Executive Function System (D-KEFS) motor score (F(2,28) = 10.31, p < 0.01) and the number and letter score (F(2,28) = 6.04, p < 0.05). There were no significant differences between the treatment responses for all three groups (no-iOCD only treated with RWR, both SCD and no-iOCD treated with SCD plugging and subsequent RWR surgeries, and SCD only treated with SCD plugging only).
