Fig. 2From: High unacylated ghrelin levels support the concept of anorexia in infants with prader-willi syndromeAcylated (AG) a, unacylated (UAG) b ghrelin levels and AG/UAG ratio c according to age in both groups: red: PWS; blue: control children. Comparative analyses were conducted using linear generalized estimating equations with a common correlation between samples from the same patients, with p-value calculation according to Pan et al. and Chaganty et al. [18, 19]. PWS vs. Controls: pâ=â0.45 (A), pâ=â0.0044 (B), pâ=â0.0056 (C), see Additional file 1: Fig. S1Back to article page
