Percentage change following 12 weeks of L‐carnitine supplementation. Percentage change from baseline group mean in (a) body fat, (b) strength measures, and (c) other functional outcomes, including long jump, 6 minute walk test (MWT), and handwriting speed test. n = 6 NF1 children, at 12 weeks one child did not complete the 6MWT due to abdominal cramping. Percentage change calculated by (12 weeks value – baseline value)/baseline value × 100. Data presented as group mean + SD. p‐Values were assessed by paired T test of baseline values and 12‐weeks posttreatment values. *p < 0.03. Each symbol denotes participants 1–6
