Table 4 Results on the full sample representing the 1644 women initially included, regardless of whether they were respondents or non-respondents. Analysis addressing the crude association (Odds ratios [95% confidence intervals]) between stage at diagnosis (advanced vs early stage (ref.)) and SEP measured by i-IDI (imputed case analysis (Model 3)) or EDI (proxy measure analysis (Model 4))

From: Using ecological socioeconomic position (SEP) measures to deal with sample bias introduced by incomplete individual-level measures: inequalities in breast cancer stage at diagnosis as an example
