Data are presented as mean ± standard deviation unless otherwise specified. The socioeconomic position by home address was analyzed based on the Israel Central Bureau of Statistics’ Characterization and Classification of Statistical Areas within Municipalities and Local Councils by the Socio-Economic Level of the Population 2015. The SEP cluster classifies neighborhoods and localities into clusters, with 1 being the lowest rating and 10 the highest. The SEP index is an adjusted calculation of 14 variables that measure social and economic levels in four domains: demographics, education, standard of living, and employment. The mid-parental height was calculated as follows: (paternal height [cm] + maternal height [cm] ± 13 cm)/2 and presented as z-scores. Delta height z-score was calculated as the difference between the patient’s height z-score and the mid-parental height z-score. Bold values denote statistical significance at the p ≤ 0.05 level
