## Plasma glucose levels in South Pacific populations

phenomenon. Tohoku J. exp. Med.

These data were read from their Figure 2d, which gives log two-hour plasma glucose
(mg/100 ml) in a sample of 89 Western Samoa females, aged 45-54.

#### Remarks:

Considering the standard errors of the estimates, this analysis is entirely consistent
with that given in the original paper. This fit assumes a constant coefficient of
variation. An attempt to find an unconstrained fit failed to converge.
