Correlation between intelligence, level of formal education, and nerve transfers for elbow flexion recovery outcomes following brachial plexus reconstructive surgery.

Additionally, patients with lower intelligence scores (<85) experienced a prolonged time from trauma to surgery (p = 0.017) and lower rehabilitation quality scores (p = 0.001, CC = 0.398).

Notably, patients with ≤7 years of education and lower scholarship levels demonstrated significantly lower BRMC scores (p = 0.049).
