Regression coefficients are shown in values (95% confidence intervals). Superscript stars correspond to significance of calculated values: * shows p-values > 0.01, and ** shows p-values > 0.001. Data on average wealth status and years of schooling are collected from national survey of household expenditure and income by the Statistics Centre of the Islamic Republic of Iran; other data are extracted from the vital horoscopes and DTARH studies
