The phrase "are unknown for study" is not correct in standard written English.
It can be used when discussing subjects or topics that have not been researched or explored yet.
Example: "The effects of this new drug on long-term health are unknown for study, requiring further investigation."
Alternatives: "are unexamined for research" or "remain unexplored for analysis".
An earlier start time, however, does not account for the BMS studies that began CSF collection at 06:00 a.m. and had a peak time of 13:00–14:00 p.m. Differences in participant sleep wake activity are unknown for all studies; therefore we cannot account for changes in sleep wake patterns between studies that may correlate with differences in peak times.
Because the true kinetic parameters are unknown for in vivo studies, gated results with high statistics can be used as the silver standard for the assessment.
Refractive and absorption indices used were 1.59 and 0.000, respectively, that is, as for latex particles and all reported results are as for equivalent latex particle diameter (the indices are unknown for many materials studied here but changes in their value to reflect these possible differences give only small variations in resulting size distributions).
Although thresholds for clinically important differences between groups are unknown for osteoarthritis, a recent study has used a minimal clinically important difference of 0.9 on a 0-10 scale (or 9 on a 0 to 100 scale) based on the median difference found in previous large trials including patients with osteoarthritis.
Although this comparison may be affected by the relative duration of HSV-1 and HSV-2 infection in participants who are dually infected (since both HSV types generally become less active over time), the time of infection was unknown for all study participants.
To illustrate this new methodology, we apply it to determine the regularity regions of a non-linear example whose firing maps undergo bifurcations that were unknown for the previously studied linear systems.
But for patients belonging to particular facial color category, the severity or degree of disease is unknown for the previous studies.
All invited subjects had previously answered two different large questionnaires in the HUNT 3 study, also covering these topics, but their responses to the questions were unknown for all involved in this study.
All invited had previously answered two different large questionnaires in the HUNT 3 study also covering these topics, but their responses to the questions were unknown for all involved in this study.
The self reported smoking status was unknown for 9% of the study population (table 1).
