“…The IHD mortality rate plus IDC in the elderly, (obtained by the second correction method), reversed some of the associations found initially at the IDC rate without correction. The associations found with the IHD mortality rate plus IDC tended to show greater mortality in districts with low socioeconomic status, which is consistent with what is found in the literature 12,[21][22][23] . However, the variable proportion of households with one resident, which previously was positively correlated with IHD mortality, started to have a negative correlation, and the proportion of households with a density of more than 4 people per bedroom started to show a weak and not significant positive correlation.…”
