Table 5.
Differences in outcome between screening attenders and non-attenders (for random blood glucose test) and, within screen positive group (random blood glucose), between those who attended all subsequent tests and dropouts, at 3-6 months and 12-15 months since initial or scheduled random blood glucose test. Values are means (standard deviations) unless stated otherwise
