Because cultural, legal, or personal considerations may affect reporting, serious adverse events may also be under-reported.
This "ghost" funding source may affect reporting objectivity.
In addition, several well-known external factors may affect reporting; for example, notoriety bias, the Weber effect, and product age [ 31– 31].
We estimated RRs that were adjusted for participant factors (participant's age and education) that may affect reporting of fibroids and exposures.
Both groups were matched, as far as possible, on real-life factors that may affect reporting skill – such as case volume and real-life reading experience.
Although our focus on these two review sources limits the generalizability of the study it is, for example, less sensitive to factors outside the review authors' control that may affect reporting (e.g. different accepted word counts in different journals).
Thus, while previous studies have primarily focused on assessing seasonal variations in alcohol use per se, the present study also examined whether the anticipated seasonal variations in alcohol use may affect reporting on measures assumed to minimize or eliminate time-dependent bias, such as QF or GF measures [ 4, 12, 15- 17].
Specifically, in all race-specific log-binomial regression models, we included participant's age and education because they may affect reporting of fibroids and exposures, and we included the maternal age at birth/birth-order index variable because it was associated with fibroids in our data and influences other early-life and childhood factors.
Socially desirable reporting as well as recall bias may affect reports of both risk behaviour and testing behaviour.
