The phrase "a sample was established" is correct and usable in written English.
It can be used in contexts such as research, studies, or experiments where a sample group is created for analysis or observation.
Example: "In the study, a sample was established to assess the effectiveness of the new drug."
Alternatives: "a sample was created" or "a sample was formed."
Futhermore, a large case-control sample was established from the German MI Family Study including 1,473 CAD/MI cases (856 male, 617 female) and 1,241 unrelated CAD/MI-free control individuals (336 male, 905 female).
Furthermore, a large case-control sample was established from the German MI Family Study including n = 1,473 CAD/MI unrelated cases (n = 856 males, n = 617 females) and n = 1,241 unrelated CAD/MI-free control individuals (n = 336 males, n = 905 females).
Given that γ-irradiation of FBS did not produce visible changes at a dose of 30 kGy, it is possible that the effects of irradiation were overlooked earlier when this γ-FBS sample was established as a supplement for the culture of NB [6] [8].
The CAFEH sample was established via a geographically-weighted randomly-selected address recruitment effort, plus a convenience sample within each study area in the cities of Boston, Malden and Somerville MA from July 2009 through December 2012.
Underlying the program is a method to convert fatigue lives tested at different cyclic stress levels into the equivalent lives at an arbitrary stress level, by which a relatively large size sample is established.
If a significant relationship between the samples was established, the mid dry period concentration (x) associated with a probability (p) of 0.10 of a level below MD and A, respectively, was calculated using the formula: p(x) = eα+βx/(1+eα+βx), where α = the intercept and β = the slope from the logistic regression.
A target of 15 000 cytologic samples was established in the hope of collecting approximately 250 histologic HSIL, providing adequate power to estimate the differences, if any, in performance characteristics between the tests.
For in silico validation of the genes, a database containing processed GEO microarray samples was established as described earlier (Gyorffy and Schafer, 2009).
