Neurophysiological assessment of comatose critically ill patients using evoked potentials have multiple advantages; being noninvasive, available at the bedside, capable of detecting subclinical injuries or providing objective measures when information derived from the clinical examination is poor [22].
To give one example, though functional neuroimaging research typically reports activation locations using coordinates, Salimi-Khorshidi and colleagues [ 5] recently showed that the consistency between a study using the original contrast maps and those derived from the coordinates alone was poor.
Celebrants wear masks and costumes for parties and for trick-or-treating, thought to have derived from the British practice of allowing the poor to beg for food, called "soul cakes".
Another important result derived from the study [ 1] was the poor correlation between different surrogate markers of atherosclerosis.
Although bias was small, the correlation and precision of eGFR values derived from the CKD-EPI formula were poor when compared to mGFR values [ 29].
Other forces acting against this institution included the influence of the Congregationalist minister, Samuel Hopkins, and also the poor profit margin derived from the trade in New England.
When he investigated the outbreak, he found it derived from the combination of low protein intake, poor soil conditions, and a lack of sufficient water resources for the thorough processing of bitter cassava roots that, due to hunger, people were consuming as their only source of food -- without proper treatment, the bitter cassava becomes laced with naturally occurring cyanide.
Critical appraisal scores derived from the USPSTF criteria were rated as poor, fair or good.
Area-based data derived from the national Census was also a poor predictor non-White ethnicity (sensitivity: South Asian 7.4%; Black 2.3%; Chinese/Other 0.0%; Mixed 0.0%).
The high variability of study methods and settings as well as the poor quality of data derived from the published literature pose major difficulties for analysis and the drawing of firm, generalizable conclusions based on study results.
