For each type of data description
given below choose the SINGLE most appropriate summary statistic. Each option
may be used once, more than once, or not at all.

4. To assess the effectiveness of a new
antenatal screening test, 100 pregnant women over 45 years of age, were
screened. 25 women subsequently had
babies with mild congenital problems. 20 of these 25 women had a positive
screening test result. 65 of those with normal babies had a negative test
result. (Answer yes/no to each statement).

smoking habits of pregnant women looking at the percentage of current smokers.
2.
In a cohort of 500 pregnant women, maternal
cotinine levels (an indicator of exposure to cigarette smoke) were measured.
The aim of the study was to see whether high maternal cotinine levels were
related to subsequent birthweight. It was assumed that cotinine levels would
have a highly skewed distribution.
3.
Adrenaline
concentrations were measured in 30 mechanically-ventilated babies at 1 hour and
24 hours to assess whether there had been a significant change. The adrenaline
concentrations cannot be assumed to follow a Normal distribution.
9. In a study of diet and epithelial ovarian
cancer, 128 women with cancer and 251 women without cancer were asked about
their consumption of dairy products. 50% of cancer patients and 10% of controls
reported consuming yoghurt regularly: (Answer yes or no to each statement):
A This
is a cohort study
B The
odds ratio is 9
C The
odds ratio is 5
D The
relative risk can be estimated by an odds ratio if the disease is rare and the
cases and controls are random samples from the same population.
E An
odds ratio of 0 indicates no difference between cancer patients and controls in
the consumption of yoghurt.
10. In a study of the effect of a new antibiotic
therapy for bacterial vaginosis in pregnancy, the infection response rate for
women on the new antibiotics was 0.4, whereas it was 0.2 in the control group (p=0.03). (Answer yes or

additional occurrence of the outcome in the treatment group

Epilepsy & Pregnancy. Question.
Some of the questions are not
SBAs as there is more than one correct answer – it should be obvious when this
is the case. I have tried to squeeze in all of the facts that might score
points in the exam and having several in one question makes the document a bit
shorter and saves me a lot of typing.
In the exam there will only be
one correct answer.

its own.
