Purpose: The present study was to use the aggregate data meta-analytic approach to examine the effects of attentional focus during balancing tasks in motor learning. Method: A literature search was conducted based on five electronic database searches, cross-referencing and expert review. Studies included randomized trials of external EF versus internal focus IF.

Virologic response to a ritonavir-saquinavir-containing regimen in patients who had previously failed nelfinavir. Interestingly, some of the benefits observed after training in working memory [ what are the advantages of a meta-analysis ] and in inhibition capacity [ 77 ] were not adavntages after this training ceased, as shown by subsequent follow-up assessments. What to add to nothing? Moreover, information regarding the control variables was also collected in both types of studies. In the case of an intervention, treatment or diagnostic test a control exposure is usually defined at the same time. Musical practice not only involves high sensorimotor integration; it also seems to be an optimal cognitive activity since it involves regular and motivated practice of progressive difficulty, with constantly renewed stimuli and tasks that represent continuous challenges for the individual [ 3637 ]. Delgado Rodríguez. Recent and past musical activity predicts cognitive aging variability: Meta-analyeis comparison with general lifestyle activities. Crit Care, 21pp. An ill-defined research question, on the other hand, leads to confused decision-making about which studies may be relevant in answering the question. Sweeting, A. The age criterion was selected on the basis of the existing evidence that cognitive [ 4 ] and cerebral [ 3 ] aging occurs most markedly around 60 years of age. Statistical aspects of the analysis of data from retrospective studies of disease. In addition to the previous section, the systematic review provided further evidences. Education, physical exercise, occupation and engagement in intellectually stimulating leisure activities have all been associated with a reduced risk of dementia [ 28 ], as well as with neurocognitive benefits [ 29 — 32 ]. SRs are an essential tool in synthesizing available scientific information; they enhance the validity of the findings from individual studies and identify areas of uncertainty where research is needed. It has been demonstrated that once several regimens have failed, the advantages of pursuing an undetectable viral load become more elusive because of the need to use more complex regimens with inconvenient dosing schedules, greater toxicity, and higher costs Meta-anaysis the language of the publications included in a meta-analysis: is there a Tower of Babel bias?.

As could be expected, the improvements were much more evident in the correlational studies, given that such studies explored older adults with an extensive musical practice and an early onset. Figure 4. Este artículo ha recibido. Boers, N. However, many of the benefits observed extend to more general cognitive functions i. What are the advantages of a meta-analysis practical consequence of this is that the random effects model tends to produce more conservative estimates wider confidence intervals of the combined effect. What are the advantages of a meta-analysis, et al. We will describe meta-snalysis methods for combining published studies. These cognitive benefits, which were particularly noticeable in individuals who had engaged in long-term musical practice, were qdvantages in both domain-specific and domain-general functions. Differences also existed in the type of control group used: passive control, music listening, or others with workshops involving various leisure activities all the participants whaat at least one physical activity.

If questions are too vague e. DerSimonian, N. Main characteristics of the correlational studies included in the systematic review and meta-analysis. From a formal point of view, SRs summarize the results of primary research using strategies to limit bias and random error. Gac Sanit, 6pp. Reuer, Although these are correlational findings, the fact that the characteristics of musical practice have a relationship with cognitive performance again supports the idea of possible causality. Grimshaw, G. Brain Research Bulletin, 67 4 Occasionally, we may find that there are no RCTs available on a given intervention and, in that case as well, we will need to analyze observational studies. Nevertheless, the best way to resolve the issue of causal directionality is to use an experimental methodology. J Neurosci. We advantwges the latter ones as they allow to do conventional analyses in the same database. SRJ is a prestige metric based on the idea that not all citations are the same. Odds ratio OR.

Resistance testing, both genotyping and phenotyping, has some drawbacks that include the lack of uniform quality assurance for all available assays, relatively high cost and insensitivity for minor viral species 5. In general, it should be data that allows the study hypothesis to be accepted or rejected. Do older professional musicians have cognitive advantages?

Musical practice, that is, musical training and performance, is one of the activities that is considered to contribute to cognitive reserve. The aim of this research was to conduct a systematic review and meta-analysis in order to compile the most relevant data to date and draw the first conclusions on the impact of musical practice on cognitive and extended relational data model (edm) aging. On the other hand, in functions that are less sensitive to the passage of time musical practice seems to be associated with an enhancing effect. Hua, J.

Among its advantages over number needed to treat and relative risk reduction is a better intuitive understanding among lay persons. Table 3. This book has two big advantages: In my personal view it is written well for someone who has at least some basic statistical understanding and for me there are quite enough practical examples and illustrations of the chosen methodology.
