From: Influence of IGF-I serum concentration on muscular regeneration capacity in patients with sarcopenia
Relation of IGF-I serum concentrations and percentage of Ki67+ expressing myocytes (A) and NCAM+ positive muscle fibers (B). Legend: Two missing values for Ki67 staining and one missing for NCAM expression due to insufficient antibody binding. Only in 12 of 31 patients NCAM expression was found, as displayed here. ß1 = unadjusted regression coefficient, ß2 = regression coefficient adjusted for sex, IGF-I = insulin-like growth factor 1, NCAM = neural cell adhesion molecule
