Abstract: |
publication bias presents possibly the greatest methodologic threat to validity of a meta-analysis / it can be caused by the biased and selective reporting of the results of a given study, or, more seriously, by the selective decision to publish the results of the study in the first place / undetected publication bias is especially serious owing to the fact that the meta-analysis may not only lead to a spurious conclusion, but the aggregation of data may give the impression, with standard statistical methodology, that the conclusions are very precise methods for identifying publication bias / methods for correcting publication bias (PsycINFO Database Record (c) 2016 APA, all rights reserved) |
