Regression weights for SEM illustrated in Figure 3.

Beta = regression weight, std. Beta = standardized regression weight, S.E = standard error, CR = critical ratio, aSEC = adult socioeconomic circumstance, cSEC = childhood socioeconomic circumstance, Edu = educational score, CIQ = childhood IQ, lesion = latent variable contributed to by regional hyperintensity scores, GMH – grey matter hyperintensities, ITH = infratentorial hyperintensities, PVH = periventricular hyperintensities, WMH = white matter hyperintensities, Hyp = treated or new hypertension. Figure 3 summarises the structure of the model. Interactions in bold are statistically significant (p
