The second type of ancillary test aims to show cerebral circulation arrest and includes digital subtraction angiography (DSA), computed tomography angiography (CTA) [8], transcranial Doppler [9], encephalic scintigraphy, and MR angiography [10 12].
Qualitative methods are not commonly used in the context of clinical trials, but when they are this is generally in the form of small ancillary components aimed at collecting data on acceptability.
The implementation of life saving therapies is dependent on accurately identifying patients with this syndrome; however, beyond clinical definitions, we lack ancillary tests aimed at this specific diagnosis.
Authoritative guidelines, such as those published by the IDSA [ 21] and the Australasian Society for Infectious Diseases [ 22], suggest a number of quality improvement ancillary measures which aim to improve the outcome of candidaemia.
We describe here the rationale and design of the CIRT-Adverse Events (CIRT-AE) ancillary study which aims to investigate adverse events within CIRT.
Several attempts have therefore been made to further develop ancillary drug with the aim to preserve the high therapeutic activity of CDDP by reducing the undesired side-effects, such as sunitinib, which could improve chemotherapeutic efficacy and ameliorate CDDP-induced nephrotoxicity in experimental animals [ 13].
This aspect is an ancillary limitation because we aimed to investigate the prevalence of CI in HD patients and not itch in acute renal insufficiency.
Ancillary but still important aims were to evaluate the impact of reduced laboratory/technical variability on risk estimates and to verify whether Bayesian statistics can provide reliable estimates in small strata.
Ancillary services market clearing problem aims to achieve social cost minimization subject to the required reserve capacity and limits of suppliers.
All cases and controls were required to have already undergone genome wide genotyping at baseline as well as profiling of seven cardiovascular biomarkers as dictated by the aims of other ancillary WHI studies.
