Data Collected at Baseline
At baseline (Table 2), higher VT scores were associated with
going out more often. Age was also associated with going out, but
sex and diabetic nephropathy were not.
Changes Over Time
Greater changes in VT scores were associated with greater
changes in the frequency of going out (Table 3), with both the
univariate model (model C1) and the multivariate models (models
D1 and E1). In the multivariate models, none of the covariates had
a p value less than 0.05.
Figure 1 shows, for each SES category, the proportion of
respondents in that category whose frequency of going out
