Promoting accelerated endothelial coverage of the stent surface, the endothelial progenitor cell (EPC) capturing stent has shown its safety and efficacy in the HEALING observational studies; however, randomized trials evaluating the device are lacking.
Another example might be that physician communication with patients about the level of evidence and experience with new devices is lacking.
Devices were lacking the refresh rate needed to smoothly translate head movements in the virtual world and had inadequate resolution and a low field-of-view (FOV) for realistic impressions.
Currently, suitable commercially available devices are lacking, and there is a growing realization that the reliance on direct exposure to patients for learning may not represent best practice from either the trainees' or patients' perspective.
Our findings indicate that robust data supporting the use of these devices are lacking.
Abolition of the human carcinogen formaldehyde from pathology laboratories is possible even in contexts whereby commercial alternatives to formalin are unavailable or are too expensive for routine use, and aspiration devices are lacking or not adequately serviced.
Typically, growth of one-dimensional nanostructures such as nanowires is readily achieved by chemical vapor deposition (CVD) [11, 13, 14], but a proper ordering of nanostructures, necessary for device fabrication, is lacking unless some extra fabrication steps are used [15].
However, research regarding the efficiency of these devices in applied settings is lacking, and fences are often ineffective due to poor installation and maintenance.
Nevertheless, despite these publications an evaluation based on real economic data coming from a study using less invasive device in high risk patients is lacking.
Defense lawyers say that despite widespread use, independent, peer-reviewed scientific data is lacking on the device's reliability and the technology it uses to measure alcohol levels.
