But other studies were less conclusive, and in any event, the absolute risk to the average woman was small.
Other studies were less successful in generating additional findings through such debrief sessions.
If the included studies were less than five, exploratory analyses were to be performed instead.
Other published studies were less selective and included all patients with a suspected diagnosis of gallbladder carcinoma.
Imaging studies encountered less frequently by students such as mammography and barium studies were less well understood.
In general, the study concludes that over time the field has become much less efficient; new studies were less likely to reveal new parts of the biochemical network.
Non-HLA candidate gene studies were less fruitful because they were mostly underpowered to detect modest effects and were frequently designed to investigate one or two functional polymorphisms, meaning that gene coverage was poor.
Studies have shown that the scales (e.g., mathematics self-concept) that had been used in PISA and TIMSS studies were less reliable in East Asia, the Middle East, and some parts of Europe, when compared with North America, where the scales were originally constructed (Marsh et al. 2013; Metsämuuronen 2012a, b; Rutkowski and Rutkowski, 2010).
Although structural mapping studies were less informative than hoped, the results indicate that the A-sheet and RCL are likely to be involved.
For example, they report that, among the studies included in their review, the proportions of RCT authors reporting an adequate method of allocation concealment did not ever exceed 50%, and in several studies, were less than 20%.
Oscillations from past studies were less robust [13], [14], [15], operated among a sub-population of individual cells [13], [14], or required highly specialized devices to be observed [13], [14], [16], [17].
