BACKGROUND: Reporting bias occurs when research dissemination – such as publication (publication bias), time-to-publication (time-lag bias) or citation rate (citation bias) – is influenced by the magnitude and direction of findings. Understanding the impact of reporting bias in imaging diagnostic test accuracy (DTA) research could inform policy on evaluating publication bias in DTA systematic reviews.

OBJECTIVES: To summarize findings from recent evaluations of reporting bias in imaging DTA research.

KEY FINDINGS:

Summarized in Table 1.

Publication Bias:
We evaluated 405 abstracts of DTA primary research presented at the Radiological Society of North America meeting. Multivariable logistic regression revealed an odds ratio of 3.6 [95%CI 1.9-6.7, p
