1 Introduction The use of the Cox proportional hazards model is ubiquitous in clinical and epidemiological research.1 The Cox model relates the logarithm of the hazard function to a linear combination of explanatory variables (or functions derived from the explanatory variables such as higher-order terms or interactions): log(h(t|X1,…,Xp))=log(h0(t))+β1X1+⋯+βpXp, where t denotes time, h(t|X1,…,Xp) denotes the hazard function for a subject with covariates X1,…,Xp, and h0(t) denotes the...

Abstract Despite decades of social epidemiologic research, health inequities remain pervasive and ubiquitous in Canada and elsewhere. One reason may be our use of socioeconomic measurement, which have often relied on single point-in-time exposures. To explore the extent to which researchers have incorporated dynamic socioeconomic measurement into cardiovascular health outcome evaluations, we performed a narrative review.
