Interestingly, despite large variations in angiographic modality choice and availability over a decade, then bar the renal angiographic threshold being reduced, the overall number of diagnostic investigations through the vascular surgical service has remained largely constant, now with a total number of studies usually between 1,200 and 1,400 per year.
Variations in ventilation modality and time among others can affect patient health [ 2].
Our results show that there are variations in the modality of treatment received in men with non-metastatic prostate cancer in the Northern and Yorkshire region.
This factor was determined to be independent of stress reactivity and sensory or motor abilities, as variations in these modalities did not load on a general learning factor or correlate with individual animals' performance in the learning battery [13].
Our primary analysis focused on mortality rates calculated after exclusion of live births under 1000 g (rather than rates calculated after exclusion of live births at less than 28 weeks) because of international variations in the modalities used to measure gestational age (menstrual based dating, early ultrasound dating, first trimester ultrasound dating, paediatric examination, and so on).
In general, variation in therapeutic modality use did not correlate with clinical outcomes, suggesting that some use of these modalities may be of limited value, and that further evaluation of these modalities is warranted.
First, it lacked a definite protocol for deep infection control, which resulted in wide variation in treatment modality among the institutions.
(NYCRIS, 2007) Looking at treatment data across the PCTs for 1998 and 1999 also shows that there is a wide variation in treatment modality by PCT (data not shown).
Also, variations in task or modality and the use of self- rather than system-paced schedules would be helpful.
While we expected variations in preferred communication modality across participants, we did not predict that the originally designed group intervention would essentially transform into a telephone outreach intervention.
