What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline (0 hr) in untargeted PBMC gene expression profile at 2 hr and 4 hr
Time Frame: Prior to the initial intervention at 0 hr and after intervention at 2 hr and 4 hr.
The venous blood samples will be taken for isolation of peripheral blood mononuclear cells. Extracted total RNA will then be used for running RNA-seq/whole-transcriptome shotgun sequencing (Illumina, San Diego, CA, USA)
Prior to the initial intervention at 0 hr and after intervention at 2 hr and 4 hr.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min.
