  1. Data are expressed as number and (percent), mean ± standard deviation, median (interquartile range). Socioeconomic position (SEP) was determined by cluster of localities of residence, ranging from 1 to 10; 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 the domains of demographics, education, standard of living, and employment (ranging from the lowest − 2.797 to the highest 2.590). The ethnicity was defined as the birthplace of the parents or grandparents (if the parents were born in Israel) and categorized according to country or region. *Missing data: SEP (n = 28, tourist medicine from Russia and the Ukraine [n = 26] and Israeli residents with paper medical files [n = 2]).
