The phrase "a specific subsample of" is correct and usable in written English.
It can be used when referring to a particular subset of a larger sample in research or data analysis contexts.
Example: "In our study, we focused on a specific subsample of participants who met the age criteria."
Alternatives: "a particular subset of" or "a distinct sample of".
This could, for instance, overcome bias arising from the fact that we are looking at a specific subsample of immigrants who, in terms of age, are at the minimum of their 'well-being curves'.
5 6 However, most of the research on SCC after stroke carried out so far is limited in that: unvalidated methods for assessing SCC were used, there was no non-stroke control group included, and the focus was on a specific subsample of stroke patients (eg, home-living patients only), thereby impairing the generalisability of the results.
In this specific subsample of C. elegans MASS and SASS genes, the overall frequency of IMMADs was still significantly higher in the MASS as compared to the SASS group (fold change: 2.31; p = 5.95E-28, by Fisher's exact test, Figure 3A and Additional file 4).
It states that different organisms live in different perceptual worlds dealing with specific subsamples of the environment as a result of their evolutionary and developmental history.
Later, after the launch of the observational study and on the basis of results, in specific subsamples of patients and in select centers of the network, a Randomized Controlled Trial will be carried out to formally compare the efficacy of alternative analgesic strategies, with particular emphasis on oral morphine (as comparator) and buprenorphine patch (as experimental arm).
Exploring gender elasticity differences for specific subsamples of the data, I find similar results across regions.
However, they did not provide detailed data for this age group and relied on self-reports of compliance or on databases covering specific subsamples of the general population.
Often strange and specific subsamples of progressing or refractory patients are selected to obtain the status of 'accelerated approval' or 'under exceptional circumstances', using the simplest possible study design.
However, as there is no available information of how this specific subsample was chosen and how the procedure was done, the results should be interpreted with caution.
Suitable sampling weights for each specific subsample are necessary for any statistical analysis of micro-data.
The tables report marginal effects for each BMI category within each age specific subsample, as well as the percentage differences of the marginal effect estimate with respect to the annual average expenditure of normo-weight individuals.
