A new preoperative bathing product is studied to see if it is
associated with a reduction in surgical site infections in
hospitalized older adults. The relative risk of a surgical site
infection was 1.11 [95% CI: 0.97, 1.24] in the intervention
group. This risk statistic means that
There is not an increased risk of infection in the intervention
group.
The risk of an infection was reduced by 11%.
There is a significant difference between the groups.
There a decreased risk of infection in the intervention group.
Correct Answers There is not an increased risk of infection in
the intervention group

A prospective cohort study examines sodium intake and the
subsequent development of hypertension. The relative risk of
hypertension in people with high sodium diets is 2.1 [CI: 1.4-
2.8]. The researcher should conclude
There is a significantly increased risk of hypertension in people
with high sodium diets.
There is not a significantly increased risk of hypertension in
people with high sodium diets.
There is an increased risk of hypertension in people who
consume a high sodium diet but the risk is not statistically
significant.
The risk of hypertension cannot be determined with the
information provided. Correct Answers There is a significantly
increased risk of hypertension in people with high sodium diets
A prospective cohort study of the effect of human milk
(mother's milk) feeding of premature infants in the Neonatal
Intensive Care Unit finds that the risk ratio for developing sepsis
during the infant's hospital course was 0.92 [95% CI: 0.85, 0.99]
for infants who received their own mother's milk compared to
infants who received infant formula. This finding indicates that
, Human milk feeding increases the risk of sepsis.
Human milk feeding decreases the risk of sepsis.
Human milk feeding has no impact on sepsis.
The impact of human milk feeding cannot be determined from
this type of study. Correct Answers Human milk feeding
decreases the risk of sepsis
A ratio always includes a measure of time.
