TL;DR: There is strong evidence of an association between significant results and publication; studies that report positive or significant results are more likely to be published and outcomes that are statistically significant have higher odds of being fully reported.

Journal ArticleDOI
The impact of outcome reporting bias in randomised controlled trials on a cohort of systematic reviews.
Jamie J Kirkham,Kerry Dwan,Douglas G. Altman,Carrol Gamble,Susanna Dodd,Rebecca Smyth,Paula R Williamson +6 more

Journal ArticleDOI

TL;DR: Direct empirical evidence for the existence of study publication bias and outcome reporting bias is shown and there is strong evidence of an association between significant results and publication; studies that report positive or significant results are more likely to be published and outcomes that are statistically significant have higher odds of being fully reported.
