A study comparing cortisol measurement by immunoassay on the Siemens ADVIA Centaur XP analyzer versus LC/MS/MS demonstrated substantial positive bias of the immunoassay following metyrapone challenge, attributable to interference on the cortisol immunoassay from 11-deoxycortisol [ 61].
Nauck et al 37 found differences in β-cell secretory responses between oral and intravenous glucose challenges that were attributable to factors other than glycemia (the incretin effect).
In a media release, Edmunds said the declines for the Japanese brands were attributable to supply challenges after the March earthquake and tsunami in northeast Japan.

20, 38 However, as recently discussed by Nichol, 56 the accurate excess deaths/winter-time deaths ratio attributable to influenza is challenging to estimate, due to the lack of available measures at the individual level.
Induction of robust intraneuronal αS pathology by exogenous Δ71-82 Δ71-82llenge does not appear to be attributable to the neonatal injection paradigm as we have observed similar findings in adult mice (Sacino et al., in preparation).
This is likely attributable to the various technical challenges associated with spinal fMRI (e.g., imaging a suitable length of the cord, reducing image artifacts from the vertebrae and intervertebral discs, and dealing with physiological noise from spinal cord motion).
Both groups indicated transition challenges from medical school to medical practice attributable to inadequate practical experience.
That case has been sharply challenged thanks to court records as more attributable to traditional police surveillance.
We challenge this notion, having observed considerable morbidity attributable to low grade organ dysfunction; the purpose of this study was to quantify postoperative morbidity.
