Anthropometric data, as well as demographic, clinical, and laboratory data, were collected. A dietary intake assessment using a 3-day food intake record was done, and the quadriceps rectus femoris thickness (QRFT) and quadriceps vastus intermedius thickness (QVIT) were assessed using B-mode ultrasound and compared between both groups.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Children with NS had lower QRFT and QVIT measurements than control groups (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).

The thickness of the rectus and vastus muscles by ultrasound was significantly associated with the percentage of protein intake (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
