QUESTION 1:
The researcher's interpretation of the study outcomes and the limitations of the study are usually found in this section of the article:
Findings
Discussion
Methods
Abstract

QUESTION 2
A study reports the average number of pregnancies in two groups. Next the columns that report on the number of pregnancies, a p-value is listed. Which of the following p values would suggest that there is a significant difference between groups on this variable?
P = .28
p < .001
p > .05
p = 0.10

QUESTION 3

Open access journal articles:
Are available only to readers or libraries with a subscription
Are limited to peer-reviewed articles
Publish only those studies that have statistically significant findings
Are available free of charge to the public

QUESTION 4
A study looking at risk for DVT uses a retrospective case-control design. A table is presented looking at outcomes (incident DVT) in women using hormonal agents compared to a control group not using hormonal agents. The statistic that will most likely be used to report on the risk of DVT is:
Odds ratio
Relative risk
Chi-square
Standard deviation

QUESTION 5

Using the table below, determine the sensitivity of the test (nearest whole number).

	Patient has disease	No Disease	TOTAL
Test is positive	70	120	190
Test is negative	30	240	270
TOTAL	100	360	460

The sensitivity is:
11%
33%
41%
70%

QUESTION 6

The stable below identified fall risk using both cross-sectional (one-time period 'snapshotIL measure) and longitudinal (repeated measures over time).

Based on the confidence intervals reported in this table, we can conclude that males had:

Higher fall risk
Lower tall risk
Same fall risk
Insufficient data to determine

QUESTION 7

Risk estimation Is based on the underlying concept of
Randomization
Chaos theory
Meta-analysis
Probabiiity

QUESTION 8

Which type of study would be LEAST LIKELY to use an experimental design?
Prospective cohort study
Correlational study
Clinical trial
Intervention study

QUESTION 9

All of the following statements are true EXCEPT:

Relative risk is expressed as a ratio

If 1.0 appears within the confidence interval for an odds ratio, there is no difference between groups

Confidence intervals provide better information than p values to judge clinical significance

values are not reported with odds ratios

QUESTION 10

The number of people who have a disease at a given point in time is referred to as:

Sensitivity

Specificity

Prevalence

Incidence
