Once data was extracted, more than 81 percent of all the abstracts did not mention any quality or risk of bias assessments (Figure 6), even though 50 percent of the articles assessed study quality or risk of bias in the methods of their articles (Sarah). Twenty-five abstracts (14 percent) mentioned quality assessment, and eight abstracts (4 percent) mentioned a risk of bias. Only one abstract (1 percent) mentioned the use of both assessments in their abstract.  As far as quality and risk of bias assessment across the three journals, Clinical Cancer Research only mentioned quality assessment or had no assessment at all (Figure 18). The Journal of Clinical Oncology mentioned either quality or risk of bias or nothing at all, and abstracts from The Lancet Oncology were the only abstracts to mention both quality and risk of bias assessments.
