The pre-operative and the post-operative groups were purposively sampled as separate cohorts to avoid familiarly with the OHS, which could comprise the validity of the results.
Within each brain region, we analyzed CTRL and HD samples as a single cohort, but note that alternative strategies (e.g., analyzing CTRL and HD samples as separate cohorts) may be desirable, depending on the downstream application.
In contrast, in the whole sample as well as in a separate analysis, lean individuals with heredity for overweight/obesity had the same relationship between fat cell volume and fat mass as lean subjects without such heredity (Figure 1B and 1D) (F = 0.04 NS).
Therefore, one should select the sampling points so that the corresponding samples are all above some threshold and the sampling points are as separated as possible.
For simplicity, we take each individual in the random sample as a separate family with size 1 so that ni = 1 for i = Nf+1,..,, Nf+Nc.
The analysis by Parks and colleagues considers its sample as two separate subgroups based on race (African American vs. white) [ 18].
These samples were treated as separate samples, because the variations in wood density from one log and within the same decay class were comparable to the variations within the same decay class when collected from a large population of logs in the field (see also Müller-Using and Bartsch 2009).

At the design level, we investigated the social vulnerability index in two separate samples, as described.
A German sample [ 14] also found evidence for association in two separate samples as well as in a combined sample with P1320 which gave a p value of p = 0.00068.
