Recall memory in patients after traumatic brain injury (TBI) at baseline and recovery over time by insulinlike growth factor‐I (IGF‐I) group. There was greater improvement in Logical Memory I (LMI) total score (immediate recall) in the above median‐for‐age IGF‐I group compared to the below median‐for‐age IGF‐I group, adjusting for age, sex, TBI severity, time since TBI, and time between scans (*p < 0.05, repeated measures analysis of covariance [ANCOVA] with post hoc Fisher least significant difference test). There was a significant increase in LMI score between scan 1 (dotted bars) and scan 2 (striped bars) for the IGF‐I group above but not below median at baseline, and no significant difference between IGF‐I groups at baseline. Data are given as mean ± standard error of the mean. Statistics for repeated measures ANCOVA: effect of time: F 1,26 = 1.33, p = 0.26; group: F 1,26 = 2.56, p = 0.12; time × group interaction: F 1,26 = 4.38, p = 0.046.
