In this paper, we introduce and study  a mapping from the collection of all  intermediate rings of $C(X)$ to the collection of all  realcompactifications of $X$ contained in $beta X$. By establishing the relations between this mapping and its converse,  we give a different approach to the main statements of De et. al. Using these, we provide different answers to the   four basic questions...

Outcomes studies of infections with resistant bacteria often do not account appropriately for intermediate variables--events in the causal pathway between the exposure and the outcome--when controlling for confounders. We discuss how failure to distinguish between confounders and intermediate variables can bias the analysis, and we address methods of approaching this issue.

BACKGROUND Statins have proven efficacy in the reduction of cardiovascular events, but the financial impact of its widespread use can be substantial. OBJECTIVE To conduct a cost-effectiveness analysis of three statin dosing schemes in the Brazilian Unified National Health System (SUS) perspective. METHODS We developed a Markov model to evaluate the incremental cost-effectiveness ratios (ICE...
