Objective: To assess upper-to-lower body segment ratio and arm span to height difference in children.
Method: The descriptive, cross-sectional study was conducted in schools of the Raiwind area near Lahore, Pakistan, from November 2021 to May 2022, after approval from the ethics review committee of the Sharif Medical and Dental College, Lahore.
