It refers to a broad set of principles and methods intended to ensure that medical decisions, guidelines and health policy are based on well designed studies of therapeutic effectiveness and benefit.
Experiences among institutions engaged in ultrasound education should be shared and guidelines and basic recommendations for ultrasound in medical student curricula should be established based on well designed outcome studies, expert recommendations, and adult learning principles.
This study is based on well log data derived from the West African Congo basin.
Our study is based on well validated government controlled national registries, including all hospitalized patients and opioid prescriptions in Sweden.
Some evidence based on well-studied proteins such as the lac repressor, T4 lysozyme, λ Cro, λ repressor, and Staphylococcus nuclease suggests that many amino acid substitutions have neutral or nearly neutral impacts on the structural stability of proteins (Kurland 1992).
The present paper provides a brief description of the physiology of the relevant target sites, a conceptual model of the two modes of action underlying local effects in the URT and the eyes, and finally an empirical approach, based on well-studied model compounds, for the derivation of a default factor for interspecies differences.
In contrast to gene signatures identified from specific patient sets by supervised methods, our approach is based on a well studied and biologically relevant model system that mimics the human mammary gland.
Therefore, we develop an approach based on the well studied model of Nowak and May [ 20] that allows to study the dynamical processes associated with the HIV coreceptor switch in combination with viral evolution.
In conclusion, though there is a lack of data based on well conducted controlled studies and further on a greater number of patients are needed, the utilization of USAD may help to minimize blood loss during liver resection regardless of the condition of the liver, even in case of cirrhosis.
This article is based on well-phenotyped patients studied with the rigorous standards of a cardiovascular outcome trial.
