Note that the magic angle effect may artifactually
increase the signal of normal tendons oriented approximately 54 degrees in relation to the main magnetic field on sequences with a short time of echo, such as T1- and PD-weighted sequences.
Transient noncardiac illness, age, male sex, and subclinical cardiovascular disease may all push up the determined 99th population percentile artifactually
Such weighted sampling could have resulted in an artifactually
higher median butyrylcholinesterase concentration in this group.
Other likely contributors to the diminished ORs in users are prodromal symptoms such as headaches and impaired cognition, which may have prevented recent initiation of mobile phone use among subjects with as yet undiagnosed brain tumors, 'lhus, some cases who would otherwise have become short-term users may have remained nonusers, leading to artifactually
reduced ORs for brain tumor in phone users, especially short-term users (and low cumulative users, because short-term use will tend to result in low cumulative use).
Interestingly, it has been observed that high glucose can also affect direct ISE resulting in artifactually
With the blooming phenomenon, the lesion may be artifactually
enlarged on long echo time images because of hemosiderin's magnetic susceptibility effect (6).
This may yield artifactually
elevated values and mislead the inexperienced clinician.
The work--whose situational point of departure was an Idaho brothel Kienholz had visited as a young man--was the artist's first fully realized "tableau" (a word he coined for it) and signaled his transition from discrete, freestanding Surrealist assemblage to the mode of immersive, artifactually
heterogeneous installation that he in no small part invented and on which he would make his name.
The increased use of highly sensitive cardiac biomarkers, particularly troponin, over time might also have contributed to both an artifactually
higher incidence of myocardial infarction and a lower level of severity among diagnosed cases.
At least one experimenter, the late John Beloff, as an extreme example, had done so many experiments with chance results that many of us teased him that he was "psi-icidal"; he must be somehow suppressing psi among his subjects, for he ought to have had at least a few artifactually
significant results by chance alone in all the studies he'd done
Laboratory data, however, should be less affect ed, and extra testing in response to the heightened awareness of influenza activity might have artifactually
lowered the positivity rate.
The bias in the sample, that patients not followed up in the one-month survey were more likely to have public assistance for medical coverage and to be male and African American, may artifactually
raise our estimation of patient's ratings of their attending physicians' communication behaviors, given that the last two characteristics are associated with lower ratings of physician communication behaviors (Hall, Elliott, and Stiles 1993).
