Example: "In our analysis, we found that a relevant fraction of the participants reported experiencing similar issues."
Alternatives: "a significant portion of" or "an important part of".
However, a relevant fraction of shared mutations significantly shifted their cancer cell fraction (CCF), while others were lost or acquired, suggesting the existence of a dynamic competition between subclones during disease progression.
A relevant fraction of the electric-field streamlines, generated by the readout voltage applied between the electrodes, develops in the air (or vacuum) volume over the electrodes.
Buildings account for a relevant fraction of the energy consumed by a country, up to 20-40% of the yearly energy consumption.
One of the most pressing issues in the study of the power generation and distribution is the characterization of the grid behavior, whether a relevant fraction of the connected power plants relies on Renewable Energy Sources.

This results in a ratio of the prompt gamma over total of about 0.35, a relevant fraction of the total coincidences.
The higher the number of images, the better the scaling, because the communication time becomes a less relevant fraction of the total execution time.
Interestingly, within the first 6 months, we observed an initial decrease of total IgG as well as ACPA-IgG serum concentrations, reflecting direct elimination of a small, but relevant, fraction of CD20+ IgG-producing cells, most likely early plasmablasts.
Moreover, in 6 patients we registered no evidence of progressive disease for at least 24 weeks indicating that a small but relevant fraction of heavily pre-treated MBC patients can achieve long term clinical benefit with this treatment option.
Measurements of ozone (O3) deposition to sensitive forested ecosystems are needed to understand the processes controlling deposition, to quantify the physiologically relevant fraction of the total deposition, and to provide data sets for developing and testing deposition models.
The pharmacologically relevant fraction of the drug is the free concentration, CFT, which is able to interact with the target, and the fND is needed to estimate CFT when only the total tissue concentration is available.
