BUS 17 Lecture Notes - Lecture 36: Publication Bias, Systematic Review, White Matter
Document Summary
Some structural mri studies have found group differences in global, axonal, and gray matter atrophy when comparing mtbi. Demonstrating a bridge between neurological damage and adverse behavioral change, dti methods have shown correlations between executive dysfunction and mtbi-related axonal injury in the dorsolateral prefrontal cortex patients with control participants. Frontal and temporal white matter damage appears characteristic of mtbi, with both relating to cognitive dysfunction postinjury. First, (a) preliminary meta-analyses tackled only a handful of existing studies at the time of their publication, providing an informative foundation, but also requiring a timely update. Sequentially, (b) studies on mtbi increased rapidly in the previous decade, with updated metaanalyses focusing on more general and specifically athletic samples. In addition to these variables, the amstar instrument provided an empirical assessment of systematic review quality, with possible values ranging from 0 to 11 and higher scores indicating greater quality.
