Most studies measure the matching quality by the amount of surplus or deficit in schooling, relative to some "required" level of schooling (Leuven and Ooesterberg 2011).
However, data on hemispheric asymmetry of emotional functions must be interpreted with caution as most studies measure relative activity of the two hemispheres (e.g. left hemisphere>right hemisphere).
Whereas most studies measure the activity of the NF-κB signaling pathway, such as nuclear entry of p65, we determined the level of p65 in the ESCC lines.
Thus, most studies measure erythrocyte GSH where GSH concentrations are high, but not necessarily a good indicator of oxidative stress across tissues.
This may relate to the fact that most studies measure stool concentrations without taking the total stool volume into account, thereby potentially concealing overall increased acetate production as a result of dilution due to increased stool volume.
For example, most studies measure the total amount of care (reviewed by Harrison et al. 2009), but this is not the same as measuring costs of care because providing better quality of care or providing care during tougher conditions may lead to higher costs.
