The effects of trans MUFAs were examined in a different way
because the number of studies was too small for multiple regression
analysis. For each single study, the difference in outcome
variables between the trans diet and the control diet was adjusted
for differences in the intakes of other fatty acids with the use of the
results from the regression analysis described above. The effects
of trans MUFAs relative to those of carbohydrates were calculated
per 1% of energy, and the results from the various studies were
then averaged.
