The parallel trends assumptions says that, although treatment and comparison groups
may have different levels of the outcome prior to the start of treatment, their trends in pretreatment outcomes should be the same (Figure 1).
No difference in IgM against Hia polysaccharide was found between Aboriginal and non-Aboriginal CRF patients, non-Aboriginal CRF patients and the non-Aboriginal healthy comparison group
, or between all CRF patients and all healthy comparison groups
The quantitative analysis used a nonequivalent comparison group
design with a baseline, end-of-year 1, and end-of-year 2 posttest.
The central, peripheral, and comparison groups
each had only one member who committed what is categorized as a non-violent crime.
This was the date that the IF group moved to their foster placements and that the comparison group
entered custody (or began their ISSP sentence).
We also found that our experimental design did not obviously affect gait measures between exercise and comparison groups
, only exhibiting some differences in reaction time measurement.
Differences between intervention and comparison groups
on measures of engagement were assessed following ramifies' final treatment sessions.
Any differences in average base year PBPMs between intervention and comparison groups
are factored out by using beneficiary-specific growth rates.

The results showed there was no difference in virus or antibody levels between children with ASD and the comparison groups

Pretest data on this measure make clear that the treatment and comparison groups
were not equivalent.
