In contrast, the theory and practice of acupuncture suggests acupuncture is more accurately described as a complex intervention, with multiple variations in its form of practice and considerable variation in the knowledge and skills of its practitioners and in the theory of healing underpinning them [ 1].
Viewed collectively, these studies suggest that there is substantial variation in the knowledge, use, and perceived influence of research and different sources of evidence across health care fields.
The variation in the knowledge and awareness of the benefit package of the different reproductive health vouchers could be attributed to limited training on specific RH issues as well as staff transfers and movements in and out of voucher accredited facilities.
Achieving this in the individual instance is challenging, given the wide range of skills and knowledge to be assessed, marked variation in the knowledge of assessment of those who must assess and the highly variable environments in which the assessment takes place.
The observed variations in the knowledge about fANC and IPTp issues among the present study respondents was possibly contributed by the different opportunities the respondents concerned had to participate in seminars/workshops or and the different opportunities obtained by the staff in terms of being supervised by the senior officers at HF or from the district levels [ 29].
The variation in knowledge, attitudes and practices across the professions illustrates the importance of including all the service stakeholders in the evaluation.
They found that 40% of the variation in knowledge (called "crystallised intelligence" by the researchers) and 51% of the variation in problem-solving skills ("fluid-type intelligence") between individuals could be accounted for by the differences in DNA.
Allelic variation data based on the knowledge of these carriers will feed into structure-activity relationship modeling to allow the prediction of likely substrates from large drug libraries [ 21], and into integrative systems biology models [ 71] using a patient's individual genotype to move towards delivering personalized medicine.
Given that SES is a complex construct including economic status (income), social status (education) and work status (occupation) (Adler et al., 1994), it is important to try to establish the contribution of different socio-economic variables to the variation in knowledge.
