Fig. 3From: Intra- and inter-rater reliability of rectus femoris muscle thickness measured using ultrasonography in healthy individualsBland–Altman plots of intra- and inter-rater reliabilities of ultrasonography to measure skeletal muscle thickness. The values from two independent raters were used to decipher the intra- and inter-rater reliabilities. Bland–Altman plots of the mean measurement against the difference between the measurements are depicted for intra-rater reliability (a) and inter-rater reliability (b)Back to article page
