3d. A case-control study was performed to determine whether head injury was associated with an increased risk of brain tumors in children. Two hundred (200) cases with brain cancer were identified from the state cancer registry, and 200 controls were recruited from the same neighborhoods where the cases lived. The mothers of the children completed a questionnaire that asked them to describe their child’s past history of head injury. The investigators found that the mothers of the children with brain tumors reported a past head injury for 70 of the cases while a past history of head injury was reported in 30 of the controls. What type of bias was likely to have influenced the findings of this study?

1. Observer bias
2. Recall bias
3. Length bias
4. Surveillance bias

ABO typing is determined by antigens located at the surface of RBCs membrane. These antigens are carbohydrates (sugars) in their structures. Different studies were reported the association between blood type and the tendency to be affected with Covid 19 (or at least the severity of symptoms in Covid positive patients vary according to their blood type).

On the other hand, blood type of person from which you get the virus plays a role in the aggressiveness of disease (this means that, if a patient with A blood type transmits the virus to type O person, the aggressiveness will not be the same as if the person getting the virus is also type A).

A hospital-based case-control study of alcohol consumption in relation to a particular type of cancer was conducted. The investigators selected patients admitted for conditions that were not related to alcohol consumption as the control group. 200 controls were individually matched to 200 cases by age and sex. Alcohol consumption was assessed by an in-person interview conducted by a trained interviewer in the hospital (suggested length, a brief paragraph each for 1) to 3) below).

1. Using epidemiological terminology, describe three potential biases which you may be concerned about in this example, and why you think such biases might have arisen.

2. For each of the three sources of bias, briefly describe steps that could be taken to control or remove the potential biases in the design of your study and analysis of study data.

3. Why was it important that the control group included patients with conditions that were not related to alcohol consumption?

4. The matched odds ratio for the association between alcohol consumption and cancer was 2.0.  Given that, create a contingency table that would result in this odds ratio based upon the matched data (note:  there are many possible correct responses to this question).
