That set of 17 also showed a severe publication bias.

Here, the body of evidence is even smaller: only seven studies during the same time period, also suffering from a strong publication bias.

This problem is known as positive results bias, a type of publication bias.

This creates "publication bias," which has become an enormous problem in the scientific community.

A meta-analysis of 380 studies in 2006 found a "very small" effect which could possibly be explained by publication bias.

A 2006 meta-analysis of 380 studies found a small positive effect within the margin that could be explained by publication bias.

That's because studies that come up with negative results tend not to appear in the medical literature, a problem known as "publication bias."

It might move us in the direction of addressing the huge problem of publication bias.

Controversy over significance testing, and its effects on publication bias in particular, has produced several results.

Furthermore, there was no indication of publication bias or significant heterogeneity.
