I offer this later idea not as a flip or inflammatory insult to those thousands who flock to this kind of fare, but as a somewhat biased, informational observation.
Since we have adjusted the protective efficacies for the effect of age at enrolment and bednet use, the potential effect modifiers, it is unlikely that this imbalance in the number of children between the groups would have biased our observation.
Many important questions are still to be fully answered, such as comprehensive assessment of numerical dynamo model biases, observation and core state covariances and error statistics, and the dynamic responses of dynamo state to the observed geomagnetic field.
Several explanations for genome shifts in nucleotide composition exist, which can be categorized into theories of mutational bias (observation that purine to purine or pyrimidine to pyrimidine changes -transitional- occur with greater frequency than purine to pyrimidine or vice versa - transversional [145] and natural selection [144]).
Questionnaire data could have been associated with possible biases – observation bias because treatment allocation was not concealed and recall bias because the educational levels of the primary respondents to the questionnaires, the mothers, differed by treatment group.
We might dismiss these as hopelessly biased Northern observations, yet these accounts gained a wide audience, and challenged the contemporary picture of the cotton south as an economic powerhouse.
The use of hydroxyethyl starch, even though limited, may also have biased our observations.
A single investigator performed all measurements in a non-blinded manner, which could have biased the observations.
