They hold that research on nutrition has not been nearly rigorous enough to date to make existing claims about the relationship between nutrition and health due a host of factors, including a lack of proper controls, difficulties in meticulously monitoring subjects, and insufficient resources to conduct the necessary experiments to show cause-and-effect.
Neither subjects nor the experimenters responsible for monitoring subjects and conducting each session were told the exposure conditions, and subjects were randomly assigned to one of six possible exposure orders (e.g., 5, 0.05, 0.5 ppm).
KR monitored subject inclusion and critically reviewed and revised the manuscript.
Logistic regression analysis was used to compare HRQL between subjects with normal weight and those with different BMI values; we monitored subject characteristics and potential co-morbidity.
The hospital has facilities for tuberculosis and HIV/AIDS diagnosis, treatment and monitoring Subjects were recruited from the patients attending the HIV care and treatment clinic.
Subjects visited the research unit weekly for measurement of body weight and resting energy expenditure (REE) and diet monitoring; subjects daily reported their ad libitum intake online.
If such issues are resolved, this method can be appropriate for identifying and possibly monitoring subjects at an increased risk of future vascular events (1, 5, 6).
We also recorded eye gaze position to monitor subjects' attention and galvanic skin response (GSR) but did not use these measurements in the analysis since in this, as in our past studies, we have found the GSR to be an unpredictable and unreliable metric [1].
In conclusion, we have developed a simple and relatively straightforward user-interface that directs and monitors subject behavior as well as acquires data.
Combining these two capabilities gave us practically instantaneous monitoring of our subject and the ability to respond to their behavior with sub-millisecond precision.
