Table 3.

Distinct models comparing WMP (cc’s) and incident lacunes (present vs absent). “WMP*Lacunes” is an interaction term. Cumulative SBP is regressed onto each set of variables in separate models. Akaike Information Criteria (AIC) scores derived from likelihood ratio tests comparing model to a null model with no independent variables. Quintiles of WMP + Lacunes selected for lowest AIC.
