This book is very referred for you because it gives not only the experience but also lesson. The lessons are very valuable to serve for you, that's not about who are reading this meta analysis of controlled c...

In studies of radiation from partially coherent sources the so-called quasi-homogeneous (QH) model sources have been very useful, for instance in elucidating the behavior of fields produced by thermal sources. The analysis of the fields generated by such sources has, however, been largely carried out in the framework of scalar wave theory. In this paper we generalize the concept of the QH sourc...

We extend the definition of quasi-finite complexes by considering not necessarily countable complexes. We provide a characterization of quasi-finite complexes in terms of L-invertible maps and dimensional properties of compactifications. Several results related to the class of quasi-finite complexes are established, such as completion of metrizable spaces, existence of universal spaces and a ve...

Randomized controlled trials (RCTs) have historically been considered the primary source of evidence to support decision-making in market access and reimbursement. However, thanks to significant progress in capturing data through computerized systems and making these data available, real-world evidence (RWE) has been increasingly considered by manufacturers and payers. Despite initiatives and r...

We investigate examples of quasi-spectral triples over two-dimensional commutative sphere, which are obtained by modifying the order-one condition. We find quasi-Dirac operators and calculate the index paring with a representant of K-theory class to prove that the quasispectral triples are mutually inequivalent. MSC 2000: 58B34, 46L87, 34L40

Although randomized controlled trials (RCTs) play a key role in modern medicine, considerable variability exists in their quality and in the reliability (reproducibility) of their results. The present article discusses features that characterize high-quality trials, such as intent-to-treat (ITT) analysis, the avoidance of patient exclusions, and a procedure for evaluating the reliability of stu...

We study reactions to entry in a Cournot model, contrasting the case where firms are endowed with unchangeable technologies against that where technologies are flexible. By the latter we mean that firms can change the installed production technique at zero cost (fully flexible technologies). We show that when firms are technologically flexible, entry can increase equilibrium prices. The analysi...

The concept of evidence-based medicine has gained broad support in the medical community, because clinical decisions based on information from rigorous scientific study are most likely to provide optimal care. Researchers attempt to answer clinical questions using either observational studies or randomized controlled trials (RCTs). Observational studies currently dominate the surgical literatur...

The CONSORT (Consolidated Standards of Reporting Trials) Statement aims to improve the reporting of randomized controlled trials (RCTs); however, it lacks guidance on the reporting of patient-reported outcomes (PROs), which are often inadequately reported in trials, thus limiting the value of these data. In this article, we describe the development of the CONSORT PRO extension based on the meth...

OBJECTIVE Poor patient adherence to lipid-lowering medication is a major contributory factor in the lack of success in treating hyperlipidaemia. The objective of this review was to assess the effect of adherence-enhancing interventions for lipid-lowering medication. DESIGN Systematic review of randomized controlled trials (RCTs). DATA SOURCES Cochrane Central Register of Controlled Trials (...
